If you read my review last year when they replaced 19 windows in the main part of the house you would know how pleased we were. They came back this week to do our sun room, 6 windows and 2 sliders, and once again perfect. As I said prior the best quality, price and service. The owner of the company is a real gentleman and he sets the tone for all employees. The installation team led by Craig is polite and meticulous in their work. We are so happy we found them, if you need windows you must give them a call, you won’t be disappointed.

I reached out to The Window Source based on a recommendation from my HOA, and I am so glad I did. Skip came out and gave me a quote for 3 windows and 2 patio doors in a 3 level townhome. He was extremely knowledgeable and helpful through the entire process.

When the team arrived, Craig was there and answered all of my questions and kept me updated throughout the entire process. I ended up needing complete rot removal/repair, and Craig (and his team) replaced all of the insulation and flashing on the sides of the home (multiple areas with rot).

I had the windows and doors replaced in June 2024, and my utility bills have gone down by hundreds of dollars a month. Even though this is a rental, it makes me so happy knowing I can pass along those savings to my tenant! I cannot recommend these guys enough, and will always pass along their information when windows and doors are needed.

The staff from the office,sales,Skip the owner, and the installers, that are not subcontracted made for a seamless convenient and transaction. They were there when they promised,when finished went through a walk trough and all 13 windows were perfectly installed. I could not be more pleased that I picked Window Source

I had 15 windows replaced (9000 series, triple paned) by The Window Source. Skip Longacre, the owner, took my order and a crew of six men did the installation. Craig and Leroy, the master installers and the other men did a great job. They were punctual, worked steadily, were very respectful of my property, and cleaned up the debris, inside and out. They are true professionals. Skip checked the work progress and there were no issues. If I decide to replace additional windows, I will go no further than The Window Source. The windows (Gentek) are very well made. I highly recommend this company. Paul Jalbert - Stratham, NH

I had several windows replaced 8/29/24 and am extremely pleased with the professional and meticulous installation by the owner Skip and his right hand man Craig as well as quality and pricing of the windows!
The entire process was a great experience beginning with Andrea in the office with the scheduling to the actual installation. I definitely recommend The Window Source of NH for your window replacement needs!!!

The Window Source Seabrook NH is the Best! Product and installation were great. Don't bother with the "other" replacement window companies. They did 7 windows for me about a year ago, I called them back to do the rest of the house (14).

We purchased 7 windows and The Window Source did a fantastic job installing quickly and timely. It's been much warmer in my house ever since! :-D

The Window Source of NH is a great company to work with. The installers, Craig & Nate, were on time, very professional and courteous and they cleaned up nicely when they were done! I love my new patio door and I would highly recommend them to my family and friends. Great job!!

About 7-years ago, I had several large picture windows and patio doors replaced at a home on the beach. They all directly faced the ocean and take a beating from wind and salt. This installation was neat and tidy. The products had a lifetime warranty but like most consumers, I wondered what would actually happen if a window needed to be replaced. After-all, it was a harsh environment - and a warranty is only as good as the company making the promise.

After 7-years of pounding from mother nature, one of the 2nd floor window's insulating seals let go and moisture developed. The business owner came out, took a look, ordered a new window and replaced it with no cost to me. Gracious and professional handling all around. I'm impressed.

After calling Skip to relay that I was a bit anxious about the window replacement as I had been recently burned by another company with incorrect installation, Skip went above and beyond to ensure that I was completely at ease by providing great communication and photo evidence of the correct installation. My concerns were heard, extra attention/effort was provided and the overall service received was top notch. Highly recommended. Thank you!

Skip and his crew were great. We are located in southern coastal Maine and they came up and were never late. Worked professionally and diligently. Their finish work was meticulous. A door jam loosened up a bit and they made the ride back and fixed it Would recommend highly!!!

The Window Source of southern NH installed new casement windows in an addition on our existing home. Communication and scheduling was excellent, installer Craig is very professional. Windows look great and match the existing house which is 40 years old. Told the owner, Skip we will be calling him again to replace a couple old windows. A+ company and customer satisfaction!!

I bought 7 windows from Window Source. There was a slight problem with one of the windows. Skip, the owner, was quick in responding and took care of the problem right away. I was very happy with the installer, Leroy, he was professional, polite and cleaned up. When he left, he took the old windows and storm windows and left me with new insulated windows.....no mess at all. I need a new front door and will certainly call Window Source. Thank you Skip, Leroy and Andrea.

We had them do our big patio door and 2 other windows a couple of years ago. Skip and his crew were great . They were on time and pleasant. We will be calling them shortly for estimate on our front door. Possibly picture window.

Thank you

Poor installation. No attention to detail and rushed the job. The windows don't slide smoothly or tilt out without scraping and were poorly insulated. I have installed a number of replacement windows so I know right from wrong.

Installation for 12 windows was supposed to take 2 days but it took 5 hours. The installers were NOT going to insulate around the frames until I insisted. They refused to insulate the bottom of the frame to my satisfaction.

They refused to install the top vinyl trim cap. This left a one inch space above the window frame which they filled with caulking. The caps ended up being left over parts.

Skip ( owner) offered to take them out and re-install (no thanks), Skip apologized and blamed it on coronavirus.

We hired Windows Source to replace all our doors (4) and windows (20) including 1 large bay window. They also did our entire house in vinyl cedar siding. Our entire home was upgraded by WD. Service was incredible and install was perfect. We highly recommend Window Source.

We bought these windows four years ago and have just replaced a sash on one. The service was perfect at every level.

Had a Great Experience with the staff and crew! Got several quotes and theirs was the best and the window quality was the exact same as the others. The instal team was friendly and got the job done on time and cleaned up wonderfully!! Side note, there was a blizzard day one of the instal!!! 20 windows, a picture window and a new slider and I’m happy! Even the kids noticed the new windows!!! Highly Recommended!

I have been doing business with Skip for 5 plus years. In that time I have had all the windows in my home replaced. Since the windows were replace 2 of the sashes leaked on separate occasions . I called The Window source and within a matter of 2 weeks there was an installer at my home with a new sash he replaced the failed one with a new sash. Today the window source team is back at my home to replace both of my exterior doors with new doors. Skip and his team are honest hard working and care very much about the home owner, customer. The Window Source have all my business and I would refer them to anyone without reservation.

Sincerely
Mark

I love my new windows. Everyone I dealt with from sales to installation was very nice. Installers were very neat, cleaned up after themselves and did a fantastic job. My husband was impressed with how hard they worked. I would highly recommend this company.

A+ EXPERIENCE ALL AROUND
Skip (the owner) was initially on the ball, quick with a price ( a great price at that), very friendly and trustworthy. He worked around my rental property needs and exceeded my expectations

Craig (the installer) is talented, fast, friendly, and trustworthy. Super clean installation, windows work and look great.

Andrea was very helpful giving me calls ahead and answering all my questions

Will use Window Source for good! Thank you!

I contacted this company for an estimate for window replacement.
After multiple phone calls 'qualifying' my level of commitment to replace my windows, the office manager set an appointment but it was certainly with hesitation and misgivings.
Once the date of appointment arrived, I was contacted again because "Skip has encountered a problem here at the office and so he won't be able to make it but are you looking for the cost before you make a commitment?" So again, we are going round and round.
The business was clearly not interested in my business. The appointment was cancelled. I will not be moving forward with this company and would not recommend them.

Fantastic Company!! The installer that installed my windows was the hardest working person I have seen in many years. He worked straight thru until everything was done. My neighbors saw the work that was done on the outside and inside and could not get over what a great job!! I am extremely happy with my new windows, prompt, courteous and excellent service. Planning on getting some more windows done by the same Company.
