"Never never buy from these thieves! We bought 8 windows to be replaced on the 12th of March 2025. The 17th of May they came to install. They didn't replace our windows. They inserted smaller windows into the old window frames(less light in the house). So now we have old cracked visible window frames. Silicone seals were not replaced. And the double hung windows can only open a third of the height, not half way up."

"I am still waiting for the return of my deposit as it has been a week since I put this review on hold after putting in the notice that day 24 June of cancellation by email and next day mail. As I have said before I am a disabled Vet, Senior citizen with health problems. I have copies of the emails that I sent on the days of 06/24/2023 and by next day Mail on the 27th notarized copies of the cancellation. Tried calling but went to voice mail. No work has been done so a rating cannot be done on the work, only the price. This job was way overpriced and never got the chance to compare. The salesman was a good person but I have my family doing it for thousands less."

"The Window People did an excellent job replacing an exterior door in my home. The contractor was very polite and capable and the door looks great and he cleaned up the area nicely when the job was done. I knocked one star off of my 'customer service' rating for the following reasons: First, he asked me if I had any caulk he could use (which I did, and which I offered him, but I think this should have been HIS responsibility, since it's something that a contractor should expect to bring with him to do the job, not something that you need to rely on the customer to supply (unlike the actual door, for example). Secondly, he asked if I had a caulk gun that he could use (which I did, but again, shouldn't the contractor be expected to bring caulk and a caulk gun to a job site where he knows he will need it?). And thirdly, he asked if I had a hacksaw that he could use to cut the molding (which I did, and which which I offered to him, but again . . . .). In any case, I am delighted with the work that was done."

FAQs for window and door contracting projects in Dover, DE

Door installation usually takes three and four hours, including removing the old door and frame, fitting the new door and frame in place, shimming it to make sure it’s perfectly level, and making adjustments to the hinges and locking mechanisms to ensure proper functionality. A door-hanging professional can replace an interior door in between one and two hours. Door installation will take significantly longer if your installer needs to create a wall opening, and it can take less time if the existing door frame remains.

If you have a problem with your window, such as broken glass, minor leaks, or a problem with your window being stuck, repairing the broken part might be a cheaper option than replacing the entire window. However, if you have a deteriorating window frame or major leaks, buying a new window will be the better long-term solution.

The average cost to install a door is around $1,100, but you could pay anywhere from $150 for a hollow-core interior door installation up to $2,000 or a high-end exterior door installation. There are a few cost factors to consider to get an accurate price, including whether your wall opening exists, the type of door, the quality and security of the door, whether you need to replace the frame, and the door size. You can expect to pay $150 to $700 for a standard 36-by-80-inch door and between $400 and $1,600 for an 80-by-48-inch door.

Window replacement costs between $180 and $410 per window, or an average of $280 per window. However, your specific replacement job could cost as little as $100 or as much as $750. Factors such as frame material, the number of windows you need, and the type of glass you order all impact the overall cost. For example, simple double-glazed windows will cost $3 to $6 per square foot, but the stronger tempered glass ranges from $12 to $14 per square foot.

It’s possible to install a door yourself if the wall opening already exists, but the work is rather complicated, and a professional installation is usually well worth the investment. For your door to work and close properly, you’ll need to shim and level the door frame in your wall perfectly, which can be difficult. Additionally, we recommend you always hire a professional door installer to place an exterior door, as mistakes during the installation process can lead to poor security for your home.
