We used Angie's List to find a highly reviewed, reputable construction company that specialized in siding. We were very pleased with the responsiveness and assistance provided as we discussed various repair options and considered possible solutions. Once we agreed on the scope of work, KCSI quickly provided a detailed written proposal. The company answered additional questions before we contracted for the work. During the waiting period while materials were scheduled for shipment, KCSI kept us regularly informed about the estimated work schedule. There were no surprises, the work was completed in one day by the hard working (and courteous) crew, and the work site was cleaned thoroughly. The actual expense was exactly as proposed and KCSI even surpassed the contract specs on several items to ensure the highest quality installation.

I went with KSCI because of the good reviews on Angies List. Mike MacCabe and his crew were great. The crew worked steadily throughout each day. Mike showed up two to three times each to check with me if I had any concerns. Mike would explain everything about the installation as the crew was doing the installation. He was open to changes and easy to work with At the end of each workday the crew spent a half hour cleaning up the worksite and stacking the unused materials. It rained several days. The crew always made sure the house was protected against the rain. Mike also showed up at the end of the day to make sure my house was protected from rain. The last day the crew thoroughly cleaned up around the house. The total cost just under the estimated price even though they made some changes I asked them to do. My house looks great.

It didn't go at all. John never provided the promised estimates.

We love working with John at KCSI. He gives great advice when we ask for a consultation and always provides several options. We especially appreciate that he doesn't try to sell us services that we don't yet need. For this project, his team installed new gutters and repaired woodwork that was damaged. They worked quickly and left no trace that they were in my flower beds - which I really appreciate! We would recommend them to anyone.

The craftsmanship and work ethics of this company was exceptional.  Every detail and option was covered and when I added two additional items to the list of required work; KCSI provided the work at a very low cost and utilized available scraps which were perfect for the small area I added.  This not only saved us money, it says a lot about the honest and dependable service this company provides.  I've received multiple complements from neighbors and friends on how beautiful the new roof and gutters look.  There were also several repair areas on the roof which KCSI repaired and shielded from Ice Dams and damage.
The cleanup and removal of old shingles and paper was also impeccable.  Great Job!
HIGHEST RECOMMENDATION !!!

Mike was very knowledgeable and informative and we have stayed in contact with him regarding the project. We are just not going to replace our windows right now.

KCSI was very responsive from the first phone call.  John Knowlan presented an estimate that was very competitive and he took the time to answer all my questions during the estimate phase.  He was very patient with all of our questions and was helpful about the solutions to our situation.   But, the real story was the work performed.  His crew of six, lead by German was very quick, thorough and professional.  On a house that was built in 1964, and had the original siding, there will be unknown issues that will be exposed.  Our house was no different and when these issues were found, John and German would meet with me to discuss the options.  They were very helpful with items that were not originally known at the start of the job.  KCSI also made several improvements to my house that were not expensive add ons. They  also cleaned up every nail and all debris.  They truly wanted my house to look good when they left.  And it does!  I would recommend them to anyone, and I will use them again when I need something.

Mike McCabe is a true professional and I trust his opinion.  We have since had Mike examine our roof and gutters.  I would use him again for sure.  And although we did not find KCSI on Angie's list I wanted to comment when I saw his company was listed.  I would give KCSI an A++.

We had an excellent experience with KCSI Construction. They replaced all of the windows in our home, installed a beautiful bay window and fixed our screened porch for us. The owner, John Knowlan, spent time with us explaining the window options that would work best with our home and was at the job every day with his crew.

We had quotes from several other companies and found that KCSI was very honest and provided high quality services at a very reasonable price. The crew did a great job with the window installation and repair of our porch, and also thoroughly cleaned up after they completed the job.  We were very pleased with this company and highly recommend them.

The KCSI company website makes claims about the quality of their work, personalized services, and experienced professionals dedicated to customer service.  Strong talk, but owner Mike McCabe and his install team also walk the walk.  I have a fairly large house that needed to be re-sided.  The original siding was aluminum, out of production before it was even put on the house 19 years ago, and probably not installed correctly the first time, leading to water damage.  I requested an estimate for replacement siding and got an appointment a day later and at a time that was convenient for me since I have a weird work schedule. Mike did a careful assessment of my house and made several recommendations with pros and cons of each.  He was able to point out and plan for likely trouble spots before even taking down the existing siding and discussed options for repair. I was aware that additional problem areas would probably be uncovered once the siding was removed and was prepared for the worst - major damage around several large windows.
Between the time I signed the contract to have the work done and the actual start date, Mike regularly updated me on the status of the siding order, delivery of materials and project start date.  On the day work started, he showed up at my door with his entire install team and introduced them by name - nice touch.  Mike was also on site for at least a portion of each day and made sure I had no issues or concerns.  As it turned out, there were fewer additional problems than I expected and Mike presented several options for resolution.  Unexpected issues included localized termite damage that was repaired at a very reasonable
price and a flashing issue at the roof line of a new sun porch ? also corrected at minimal cost.  The only ?major? issue was one large picture window (1 of 4) that had totally rotted across the bottom sill and could only be fixed for the short term.  The other 3 windows had some water damage but Mike and his team were able to save them.  I was actually anticipating having to replace at least two windows.   Mike gave me a number of options for windows that would be suitable as a replacement  and worked with me to make sure the window I chose met all my needs ? both functionally and cosmetically. 
I should note that in addition to the siding, Mike?s team replaced all the aluminum used to wrap the brick molding.  The previous wrap job wasn?t really holding up and didn?t look good, even when it was brand new.  His install team replaced it all and it looks
amazing ? crimped to match the brick molding exactly, complete with mitered corners.  My house looks brand new and I won?t have to worry anymore about painting trim or wood rotting!
Bottom line: Mike and his install team did an amazing job.  The job was priced fairly and the final bill was incredibly close to the original estimate - so very few surprises that were not included in the original estimate.  The open lines of communication/quick response with Mike removed all angst normally associated with a large renovation project.  I'd recommend you not even bother getting other estimates and just go to KCSI for any roofing/siding/window needs.  

Everything about their work was excellent.  We were extremely happy with both the quality of their work and their customer service.  The owner was regularly on site.  He patiently explained every part of the work.  The crew worked very hard and made sure the trash was picked up at the end of every workday.  We strongly recommend this company!!

I had him out to give an estimate. They were originally built with aluminum and wood planks. Someone put cheap siding on. He brought out different products and I went with insulated. He brought me separate styles in large sizes. I taped them on my house and it helped narrow the houses down. Extremely punctual, very clean!! They even made sure the street was clean! He worked with my roofing contractor. They did a walk around and answered all my questions. He told me to check it and he would come back. Absolutely no problem and my house looks great! The whole house looks sharp! He is super personable and makes you feel like family

Looks great.  Prompt service, up front pricing and information, very professional.  Definitely recommend.  We had to pay the minimum labor cost which was $600 I think, then the materials were the rest.  Overall, not bad.

If I could give KCSI an A+ on Angie's list, I would.  I joined Angie's because of the dearth of trustworthy contractors in the DC area and because of one extremely negative experience I had last year.  KCSI was fantastic.  John came out to our house several times to get a sense of the job, always working with us on the time--both my wife and I work.  I have a very restrictive BAR in my area and John provided me with both materials and brochures that I could take to my BAR to assuage their fears.  Given the expense of the project, KCSI was willing to do it in phases over the course of several months to help us absorb the cost. Few other companies were willing to do this or wanted to add a surcharge.  KCSI's estimate was by far the lowest of the 8 we received and despite the discovery of extensive rot that was not anticipated, KCSI did not hammer us on the cost of the additional repairs.  John was also extremely great in working with us when we realized that we needed a pause because our infant was unable to sleep with the project ongoing.  Communication was great--John let me know where we stood at every phase of the project and what was accomplished each day.  I have never seen a contractor clean up like KCSI did--usually, there is trash, nails, junk, etc.  I was hard pressed to even find a paint flake in my grass!  The work is top notch, KCSI was flexible, extremely competitive on the cost, and John was forthright and earnest about everything.  I will certainly turn to them in the future for anything I need done on my home.

KCSI did a fantastic job and we couldn't be more pleased with the quality of the work and how our house looks.  We had estimates from two other respected companies, but chose KSCI because of the quality of the estimate/consultation, competitive price, and reviews about attention to detail. They did not disappoint. John K. oversaw the project and kept us informed throughout the process and responded to all of our questions/concerns. The crew, led by German, was incredibly hardworking. They were professional and affable throughout the project. They did a great job cleaning up and taking care of final touchups.  The company even used left over material to re-side and install trim on our storage shed abutting the house -- this detail was a big and welcome contribution to the project.  We would highly recommend KCSI because of the quality of their work and attention to detail. Throughout, we felt that we were working with a company that we could trust.

I had originally met with John Knowlan back in 2009 for some leaks around my roof ridge vents. He gave me estimates, and then I put off the repair for 4 years. 2013 summer rains caused major leaking so I needed to get this repaired before the winter.
 I called John in October 2013. He pulled up the old estimate and agreed to use same price. I also added more work.
John was really easy to work with and he also supplied various options and recommendations (ie do entire roof, replace/upgrade sheathing, etc.). He was very detailed oriented and was double-checking the job all day.
Work conducted was:
-Remove top roof ridge vent, replace all bad sheathing, shingle over new sheathing.
-Replace all top roof pipe collars.
-Remove and replace ridge vent on lower roof.
-Replace any worn shingles.
-Remove and replace front upper gutter with larger size.
-Remove and replace front lower roof gutter.
-Remove rotted gutter spacing wood on soffits and replace with pressure treated.
-Add new larger downspouts to both.
-Install gutter covers (I supplied material).
-Conducted paint touch-up as needed.
Job was started and finished in one day. Crew of 6 or 7 guys went immediately to work on all areas and were very easy to talk to/work with. No communication problems . All debris was cleaned up. Work looks great!
I thought this was a very fair price for the amount of work completed. I would not hesitate to call KCSI back for another job and I have already recommended them to my other Truro neighbors.
 

He did not follow thru with an estimate.

The job went very well. They were done in the time they said they would be done even with the rain. They were at the house by 7:30 and left around 5:30 each day. They cleaned up at the end of the day before they left and were conscientious of our family as they worked on our home. They told us how to prepare for installation and what to expect. I asked for a little extra detail on the trim of door and they were able to do exactly what I wanted.   (pictures available)

KCSI was upfront as to what they could and could not do:  Roofing was not their specialty, but most definitely replacement of a box bay was (up to then, I had difficulties finding a contractor who could do the work).  John Knowlan could not have been more helpful.  We met at a townhouse complex nearby so that she could show me 3 different box bay options -- I really appreciated the extra effort he made to do that -- when he provided me 3 different quotations, I knew exactly what I wanted.
The crew of about 4 men ripped out the old box bay and replaced it with a much improved, sturdier version, using Azek PVC trim boards. The team put in two full days in extremely hot and humid weather, and completed the task.  John came by several times daily to check out the progress.  They cleaned up thoroughly before taking off.
I had before and after photos ready to post, but it doesn't appear that Angie's list accepts photos anymore!
I was very pleased with KCSI's work, and would highly recommend them for any exterior job.

I had an exterior wall made of T1-11 MDF which was buckling and cracking both vertically and horizontally.  It was two stories plus the attic rake on top of a walk out basement, so it was a good 3-1/2 stories to the top of the roof.  The original cedar wall had been replaced by another contractor in 2006.  Unfortunately, I was traveling during the time the wall was put up in 2006, so I didn't see how it was installed.  I knew that it had been done wrong when I got on a ladder to put some nails into the seam to flatten it out and it never hit a stud.  Additionally, each story did not overlap the one below it as it had been in the original design.
KCSI offered to fix it correctly by removing every back down to the studs if necessary and building it back out correctly.  I requested that they use a cement fiberboard that looked like T1-11 for the exterior due to the unrelenting heat it gets from the sun.  They also recommended a change to my materials list for some potential wet areas from run-off.
They needed to replace a boatload of trim all around the house that had taken physical abuse over the years as well as deal with a couple of ugly bay window panels that I've disliked since I bought the home.  They brainstormed how to deal with it and were very creative in coming up with multiple possibilities until we came up with the perfect solution.
They also needed to repair a hole in one of the panels on the back.  Birds had been nesting in the wall for a couple of years.  Although I told them I'd be happy with whatever they could do, the repair was almost invisible.  They were pretty proud of that repair and had every right to be.
Finally, I had an issue with water running down between the house and the garage.  The original builder apparently just built the garage right up against the finished cedar panels of the house.  KCSI did a superb job cutting a strip out of the paneling to put the correct z- and step-flashing in place with new trim boards.  They did the same with a mid-line rake in the center of my roof which had been ignored for years.  I have no concerns with water coming in any more.
They were fast, professional, and reasonably priced.  John was a pleasure to work with, German (John's foreman) knew his stuff and came up with many of the solutions, and the entire crew could not have been better.  I am an extremely picky customer when it comes to a final product being done right.  A few contractors have complained that I was too picky.  I'm not. I just expect them to do a better job than I could do myself.  But KCSI's work was top notch.  I would use them again without hesitation.  It went so well, I told John to feel free to use me as a reference.  I have never done that for any other company.

KCSI was unable to complete the needed work because it was outside of their specialty, but Mike still made a trip by my house and provided a complete list of recommendations of what he thought needed and could be done with the house exterior.  He went out of his way to help me and this is a mark of a true professional and a company you can trust.  I will definitely call him in the future if I need work done.

They did a great job, they were very responsive, cleaned up after themselves, I was very happy with this company.

John showed up for the estimate when he said he would.  He provided photos of the needed work plus the estimate the next day.  The quote was very fair.  The work was completed the following week.  We are extremely happy with the professionalism of John and the superior work provided by his crew.

The original service was performed in Nov 2011.  They did an excellent job.  Unfortunately, a window was leaking and Mike and his crew came back to seal the window.  They had to remove the siding from the 1st floor up to the top of the 2nd floor to determine the leakage issue.  They performed the work in sealing the window in 1 day.  My wife and I are very impressed.  I had originally submitted the positive comments on their work in the early part of February, but for some reason, it was not posted.  I apologize for that.  I would definitely call Mike MacCabe to do similar work in the future.  Thanks again, Mike.
