Warranty FAQ/Service Form

My window will not lock
This is usually due to the top sash moving down. Push the top sash up and the bottom sash down (opposite directions). The meeting rail should line up and allow the window to lock.

The bottom sash on my window will not operate
This is generally a result of the sash coming out of the clip in the frame. Often the clip is then ‘jammed’ to the bottom of the window not allowing you to put the sash back in the clip. If the clip is jammed down, take a flat head screwdriver and gently pry the clip up at least ½ inch from the bottom of the window. The sash should then be able to be seated in the clip.

What maintenance is covered?
General maintenance is not covered by manufacturer or Allied warranties. In fact, lack of regular maintenance can void some warranted items. So – things like general cleaning of siding and replacing broken down caulk ARE NOT covered but ARE recommended. For details on cleaning and caulk, visit the applicable manufacturer web site below.

What is seal failure?
Seal failure is when the IGU (insulated glass unit) in a window fails and allows air to enter the sealed unit. This will result in significant fogging of the glass within the sealed unit. So – try to clean the windows and determine if the fogging is on the inside of the unit.

The shingles on my new roof look wavy.
Shingles are fairly rigid. They take time to completely flatten on the flat surface of your roof. Depending on the time of the year (outside temperature), it may take a few weeks for the shingles to all lie down.

What Our Customers Are Saying


If you want to save time and money, go to Allied Siding and Windows first! We worked with a big box company for 5 months and they were never able to deliver and install the product we had requested. Allied had it done in two weeks, at a cheaper price and the house looks great!

Susan W

I love Allied. I have used them on multiple occasions, and they did a great job. Their representative was a wonderful salesperson who knew the product well, and working with the office at the beginning to get this all set up was a pleasure.

Kate J.

I contacted Allied with a last-minute project of adding siding to my home and they were prompt getting back to me and even fit the sales presentation into my very busy and crazy schedule, and he came out on a Saturday morning to meet with me. The estimation process was made quick and easy.

Diane H.

I purchased gutters from Allied for my home. My salesman was very professional and knowledgeable in explaining the different materials and colors along with associated costs. The entire process was quick and efficient! I would strongly recommend. The installation team was polite and courteous

Joann S.

Great company to work with. Ease of business. Quality work. Truthful experience.

Scott M.

Quality, workmanship, and value. We continue to enjoy our choice from three years ago – our choice was Allied Siding & Windows!!

Barbie C.

We had 19 Simonton Generations replacement windows and James Hardie siding done on our home of 22 years by Allied Siding & Windows, here in northwest Houston (Tomball area), in the summer of 2013. It has been almost 3 years and it all still looks brand new, inside and out! The workmanship and attention to detail is why we chose Allied in the first place. I cannot believe how quiet the argon gas-filled windows make our house; besides keeping it cooler in the summer! Our dogs cannot even hear the fireworks on the 4th of July anymore! We had someone stop by our house just last month to ask us about our siding and trim colors and asked if they could look around and take some pictures!

Dan R.

I used Allied Windows on my previous home, and when I moved, I never even checked the competitors. Extremely pleased with their work and prices.

Robert A.

I was very happy with everyone that I dealt with at Allied, from the office staff, my salesman, the crew leader and his entire crew that installed my windows and siding. Everyone was truly professional, courteous and kept me informed on my repairs. The painting was like artwork and the crew did a great job of clean up before leaving. This company is exceptional, and I chose them based on Matt Patrick’s endorsement from KTRH radio. I would not hesitate to recommend Allied for your home repairs. Thank you Allied for a great job!
