"The contracted the work off to a third party. Jon took longer than expected. The windows was installed pretty good from the looks. Communication could have been better with knowing the job will take longer and what types of trims I wanted for the windows. As the contractor that was hired for this job by this company. Did a good job with putting up decent trim. As for the new windows they look great. I purchased the myself and hired sentri homes to install them. I will need to have a my siding on my house redone to be closer to the new windows so the gaps are not so obvious. That was not expected at first. But from old storm windows and not knowing how they were put in originally. There was some unknown things that was learned from the job being completed. I will have the siding of the house slightly done to match really good for what I wanted later on. My only concern is better communication with sentri homes. Overall they were great when I did talk to them."

"NE Renovations is a general contractor whose network of contractors provided services to me as I was getting ready to sell the house.  The electrical service went very well with Mr. Martucci doing great work and advising me about things that did not need to be done.  I feel that he was a great advisor!
The flooring in the basement also went very well with the NE folks advising me about the best way to approach the installation.  Everything was perfect when they left.  I truly appreciated their workmanship.

"I'm hesitant to say how awesome Shapiro Construction is because I would not mind keeping them all to myself. But they helped me so much, I want to give others the chance to choose their services. First, Mr. Shapiro is incredibly talented in all the things! Carpentry, electrical, plumbing, HVAC, all of it, and he knows Code. I hired him for 1 project and then immediately hired him for 3 more! Bring him your weird problems, the jobs other people botched, the stuff you aren't even sure is possible. He will find a way to make it happen, and the work will be structurally sound (he made my old 1850s house stronger than it was before!), with a beautiful aesthetic. Moreover, he will clean up his work area at the end of every day. He is a good communicator, and shows up on the days he says he will! Reliable, talented, a good listener, and eager to involve the client in all the decisions--I give Shapiro Construction my highest recommendation. They will not be your lowest bid, but they are well worth it. The other guys who bid lower are the ones who use shoddy materials, leave the jobs half finished, and then don't come back again or return your calls for weeks. Mr. Shapiro gives clear timeliness. Pay a little more for the quality work and the better service of Shapiro Construction. It will be worth it for a headache-free job working with someone who collaborates with you and responds to the individual quirks of your house, and guarantees a beautiful finished product. I know my house represents a better long-term investment because of the work done by Shapiro Construction."

"Originally I had a different contractor lined up to do this work.  At that contractor's request I purchased an 8 ft slider in pieces to be assembled rather than as a module (already put together).  My original contractor delayed and delayed so I hired A few good tradesmen to come in and do it instead.  They did a great job.
First Brian came over to look at the door and give me an estimate for the work.  He was running late but called to let me know and to make sure it would still be a good time to come.  The quote was higher than what my original contractor was going to charge but I liked Brian and just wanted the door installed so I went with it.  I feel like I got my money's worth.  
Brian's guy, Sam came on Saturday morning to do the work and was right on time.  As I mentioned, the door was in pieces and needed to be assembled and installed.  Generally a sliding door comes pre-assembled as a "module".  I had a couple of other contractors come to look at the door.  They both said they had never seen one like this before and they never got back to me with a quote... Right away Sam told me that he had done a lot of sliders but never one that required assembly like this before.  He took the time to study the installation instructions and figured out how to install the door correctly.  
On the non-operating side of the slider, A deck railing post butts right up to the seam between the wall and the new slider.  Normally this seam would be sealed with silicone.  Because of the way the post butts up to it, it's impossible to get the silicone in there.  Instead of just hoping I wouldn't notice (which I probably would not have), Sam showed me the problem and explained that he put a lot of silicone in-between the wall and the door so it should still be water tight.  I appreciated his honesty, which is rare in my experience (especially with contractors).  
Whenever I need anything done on my home I will definitely be calling these guys first.  I've already asked them to come back to replace a window for me.  I highly recommend them.

"Brad and his dad were great. They were always at the job on time. They kept me informed each day during the entire project. They are certainly experts with old houses and were happy to explain what they were doing and why. I would certainly have them back when we replace the front doors if we find the sill is rotted. Great guys. Great job."

Home Building questions, answered by experts

In most states, you can build an in-law suite on your property as long as you follow local building codes. However, it's important that you have enough space on your property to accommodate the new structure. A functional in-law suite in your backyard will require between 300 and 800 square feet of space.

Modular homes are a type of prefab home. Specifically, manufacturers first build modular homes in sections and then deliver them to the job site. The modules, or sections, are usually at least 70% finished before they arrive on your property.

In comparison, prefab homes arrive in panels or segments, and workers assemble them on-site. Generally speaking, modular homes tend to be more durable, and their consistent construction standards may mean you’ll have an easier time getting conventional home loans.

To get a quote from a builder or general contractor, contact them over the phone or online and explain your project. If you already have house plans drawn up, they’ll need to review them to determine the project's scope before providing you with a quote. Ask for your quote in writing and compare quotes from several pros before choosing the best one for your needs.

One of the best ways to negotiate with a homebuilder is to forgo price reductions. Instead, negotiate over upgrades and incentives, as many builders are more willing to go down that road than to decrease their own fee. Even if they were willing to take a cut, a reputable homebuilder often knows their worth, so a willingness to negotiate could be a red flag. Beyond that, builders are typically willing to negotiate closing costs instead of offering a discount on the base price.

Building a house without blueprints is not advised. It will prevent you from obtaining necessary building permits and meeting building codes and is likely to result in shoddy construction and unsafe living conditions. Detailed blueprints ensure that a house is built to exact specifications and is constructed safely and structurally stable.
