Very professional, very skilled, very reasonable, and very reliable. If you need egress windowsâ ¦look no further."

"Very happy with the work done and the price."

"Superb!  First off, the customer service and response time was great!  Kevin came to the house to assess and ended up giving us a wealth of information and education to help with potential "problem spots" in and around the home.  He gave us options instead of directing business only towards him (aka: wasn't trying to make a quick buck)--THAT alone makes me trust him and his business which is HUGE in today's world. We need more business owners like Kevin--ones we know are not trying to take us for a ride on the financial train!  Hats off to Kevin!  If we ever need him in the future--we will not hesitate to call him!  I HIGHLY recommend The Leaky Cellar! Many blessings to Kevin and his business.

I just moved.  Sellers had replaced all windows except in the basement.  Needed egress for basement bedroom. 







Installation dates were changed but they did everything they could to get 4 windows in before new deck was installed. 







There was miscommunication on the kind of windows for the downstairs rec room, which was under construction for remodel.  In that room I got 1 slider and 2 double hungs.  Not what I would have wanted if I'd understood.  It was miscommunication, but I told them it would've been helpful if they'd even drawn a picture or pointed out that there would've been two different types of windows in the same room.  We wound up constructing the room so the different windows would not be in the same room...made the storage area larger than intended, but it works.  Initially they said they'd change out the 2 double hungs.  Then they missed a couple appointments when they were to come back and install the 5th window.  At that point, I said, yes, go ahead and replace the 2 double hungs and just make it right.  They said they would but they would charge me full price.  It wasn't worth the aggravation since we

hadn't started putting walls up yet.....and were able to make it work.







Overall, this is a good deal.  I don't regret purchasing or working with them.  Ask lots of questions and make sure you completely understand the order!!  I do think they should've been willing to stand by the original offer and replace the 2 windows.  The expense on their part shouldn't have been more than labor since the windows could've been used on another project.  I would've split the labor cost with them. 







One of the missed appointments on the 5th window was due to their supplier being closed Labor Day weekend.  Since I was taking time off work and trying to work around their schedule, more communication and advance notice of the delays would've been helpful.  The entire process just had a few bumps!!

"Overall very nice guys, did a good job and I would recommend. That being said, there was good and bad that I think everyone should know - and should ask all pros about. Positives: 1. Window was installed professionally 2. All parts installed correctly and done well 3. Completed in the time frame specified 4. Nice guys that were amicable Negatives: 1. They didn't clean up - left large mess of drywall on the interior that I had to clean up 2. Bad dry wall cut - they cut it greater than 4" outside the cut in the concrete, which made it very difficult for interior framing of the window without replacing drywall 3. Trampled shrubs - they dug up the plants and shrubs, but then trampled on some of them 4. Dead grass - machine to dig out hole ripped a lot of the grass out. Also, a lot of mud was in the grass that required work to rake back into dirt areas and off the grass Not positive or negative, but be aware: 1. Settling - the dirt around the egress window settled by nearly 2-3 feet! Requires follow up to fill in the hole 2. Excess dirt - plan for a very large amount of excess dirt"
