Posted on Joseph LippoldTrustindex verifies that the original source of the review is Google. I had been getting estimates from companies for roofing & siding for my townhouse. I came across window doctor while on google, I called and they were able to have someone come out imminently the same day. John was awesome, he definitely knows the products in and out. John also went above and beyond to do demonstrations of how the window operates & how much heat will be staying in my house rather then it escaping through the old windows & siding, and vice versa with A/C. No other company I had come out did even half the things window doctor did to make me feel comfortable In the decision I was making. There was NO pressure John was very reassuring and told me all of my options financially. The biggest surprise for me was at the end when John gave me the estimate the price was a lot less than the other estimates I received. Now that the windows and siding are installed I can definitely feel the difference with the heat not escaping the house, my house looks completely different and we’ve gotten so many compliments. I am beyond happy and satisfied, I will definitely be recommending Window Doctor to any body that needs work on their house! Thank you Window Doctor !!!Posted on Sam WilsonTrustindex verifies that the original source of the review is Google. I had my windows replaced recently — a big picture window and several double pane windows — and I’m really happy with how everything turned out. The crew was fast, friendly, and really knew their stuff. They answered all my questions and made the whole process easy from start to finish. The new windows look great and have already made the house feel more comfortable. Everyone was kind and helpful, and I’d definitely recommend them to anyone thinking about getting new windows.Posted on Charlie WallaceTrustindex verifies that the original source of the review is Google. Window Doctor did a great job on my new windows. Fair price, quick turnaround, and no issues with the install. Windows look awesome—would definitely use them again.Posted on David LeeTrustindex verifies that the original source of the review is Google. ⭐️⭐️⭐️⭐️⭐️ We couldn’t be happier with our experience with Window Doctor! Before deciding, we got 4 different quotes from other companies, but none of them came close to the professionalism, pricing, and confidence we felt with Window Doctor. We had 17 windows replaced along with Coventry siding, and the entire installation was completed in just one day. The crew arrived on time, worked efficiently, and left our property spotless. The quality of the windows and siding is outstanding, and the difference in both comfort and curb appeal is incredible. From start to finish, everything was smooth, transparent, and handled exactly as promised. We highly recommend Window Doctor to anyone looking for windows or siding—you won’t be disappointed!Posted on JoyceTrustindex verifies that the original source of the review is Google. New review ⭐️⭐️⭐️⭐️⭐️ We had a new front entry door installed along with all new maintenance-free wrap on our exterior wood and fascia. The finished work looks great, adds so much curb appeal, and we don’t have to worry about upkeep anymore. Everything was handled professionally and we’re very happy with the results.Posted on Robert VereenTrustindex verifies that the original source of the review is Google. What stood out to me about Window Doctor was the value. They gave me a price that was locked in for a year, and they even matched a competitor’s quote. The installation was precise, and I have peace of mind knowing the windows are backed by a lifetime warrantyPosted on Nicholas LunaTrustindex verifies that the original source of the review is Google. John and his team are amazing. I can't say enough good things about him and his professionalism. His quality of work John is one of a kind just so everyone know is just in case it's a two window minimum so if you're looking for one window to be fixed or repaired or to be replaced John's not your guy but anything else you need any more than one window call John I promise you you won't be disappointed.Posted on Karen SmithTrustindex verifies that the original source of the review is Google. Easy presentation, didn't feel like I was pushed- they gave me options to choose from, and I was able to make the decision that was best for my house and my budget. Great team and great service.
