Real People. Real Results.

We recently had several windows replaced by Window Doctor, and the results have been incredible. Our home had older drafty windows and our BGE bill was reaching almost $600 during peak months.


After John and his team installed our new custom replacement windows, our latest BGE bill dropped to $214. That difference alone speaks for itself.


They took the time to measure everything carefully, explain our options, and make sure the installation was done perfectly. The crew was professional, clean, and respectful of our home throughout the entire process.


If you’re in Anne Arundel County, Severna Park, Pasadena, or the Baltimore area and dealing with drafty windows or high energy bills, I highly recommend calling Window Doctor. The quality of the windows and installation is outstanding.



Great company, great people, and real results.

We had our windows replaced before selling our home, and it was one of the best decisions we made. They were able to repair the rotted wood around the windows, which increased the value of our home. We actually made money from the upgrade! The turnaround time was fast, and the whole process was smooth. I would definitely recommend them if you’re looking to replace your windows before selling.

⭐️⭐️⭐️⭐️⭐️

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!

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.

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.

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.

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.

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 !!!

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 warranty

Love my new windows and sliding glass doors! The crew was super nice and helpful, and financing made it easy to get it done. Looks great!

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. Thank you, Window Doctor.

I recently had my windows replaced and I’m really happy with how everything turned out.

The process was straightforward and everything was explained clearly without it feeling like a sales pitch.

Installation went smoothly. The crew showed up on time, worked efficiently, and cleaned everything up before leaving.

The biggest thing I’ve noticed is how much more comfortable the house feels. There are no more drafts and everything feels tighter and quieter. The windows also made a noticeable difference in how the house looks from both inside and out.

Overall a really good experience.

Great job. Working with John was easy. Efficient from start to finish. Highly recommend this company.

Continuing issues post installation and communication has been extremely lacking. Called my sales representative multiple times with no call back.

Sales number of returned calls is masked and doesn’t resolve back to the salesperson.

Several excuses were given from as to why no contact had been returned. And I had to call every time to learn this.

I’ve finally spoken with Alside (the manufacturer and actual installer) and a resolution is in progress.

I’ll update my review when it’s completed.

Update: communication does seem to be improving after I raised concerns loudly enough to get attention.  The work done has been very good. The issues are largely cosmetic and they are working with me to get them fixed.

More to come
