Customers say: Quick response

"Chris was very polite and seemed personable and professional when we interviewed him for the job. He and his helpers were on the ball about getting the project completed in an emergency situation, however on the final day of the project he said the job was completed when he and another worker installed some upper kitchen cabinets in about 3 hours, when it was actually left unfinished. His hourly rate was quoted at $35 per hour; he really didn't give us a quote for the entire project. He charged us 8 hours per person that day, as well as a number of other days, whether they were there 3 hours or 8. Also, after some demolition we discovered this project was covered by insurance and we found that his repair costs rose dramatically when he knew insurance was paying for it. He did return to finish up the trim work and cabinets when I called and complained. For these reasons we won't recommend or hire him again."

"Palmer Construction — Highly Recommend I called Brad at Palmer Construction about a roofing issue, and from the start he was thorough and professional. He came out to the house, took detailed notes, and gave me an extremely fair price. Once he and his crew got up on the roof, they discovered the damage wasn’t as extensive as originally thought, and instead of running up the bill, Brad was completely honest about it. He was transparent throughout the whole process, showed me everything, and walked me through exactly what needed to be done. Since then, he’s also handled several small projects around my house, and every time it’s the same story: reliable, detailed work done the right way. He really sets you up for success. I couldn’t be happier with Brad and his team, and I’d recommend Palmer Construction to anyone in need of quality, trustworthy work."

"I am extremely happy with AJ's service, start to finish. We initially reached out for an estimate at the beginning of 2015. A representative came to our house to explain all the different products as well as pricing and timing. I had reached out to 2 other companies before hand but was not comfortable their high pressure selling. AJ was very patient with us regarding our timing and budget. I received an estimate on the spot and was able to take my time to review and get back to them. We scheduled the work for May and was able to have 7 Windows removed and replaced in only a few hours. We are very impressed with the quick respond time, professionalism and quality of work including cleanup. We plan on using AJ to replace the remaining Windows as well as a sliding glass door in early 2016.

"Mr. Ferrell first connected his computer to my computer via internet and worked for quite a few hours trying to determine what exactly was wrong. The next day he continued working from his computer for several hours. He determined he would have to have my desktop tower to complete the repair. He and my son met in Huntsville to exchange the tower. He then cleaned up a lot of what was wrong and reloaded Windows 10. He deleted the D: drive which had way too much memory allotted to it. The tower was returned and I plugged it all back together and it is working better than it did when I first purchased it. I would use him again and I recommend him highly to anyone needing computer updating and/or repair. His work is warrantied and he is very personable, knowledgeable, and helpful."

Window Door Contractors FAQs, answered by experts

Window seals don’t last forever, so they’ll inevitably fail for one reason or another. One of the most common reasons is the expansion and contraction of the glass. When the glass gets warm from sunlight, it expands and adds pressure to the seal; at night, as the glass cools, it contracts. This process, day in and day out, can eventually cause the seal to fail. Other common sources of failure include the house settling over time, chemicals that damage the seal when repainting windows, and incorrect window installation.

If you’d rather repair your screen door mesh than replace it, you can patch it. Purchase a mesh patch for screen doors with small holes or tears, especially if the mesh is pretty new. Hardware stores and websites sell mesh patches that are easy to apply with an adhesive or a warm hair dryer. Keep in mind that repairs won’t look as aesthetically pleasing in most cases as a full replacement. 

A vacuum with a hose attachment or a lint roller can easily remove dust from your window screen. Pressure washing window screens is another option, but you should make sure you have the appropriate nozzle and pressure setting to avoid doing extensive damage to your window.

The cost of a window repair varies significantly depending on which part is damaged. Here is a breakdown of common repairs and their estimated costs:

  • Broken seal or fogginess between panes: $70–$245

  • Cracked pane: $40–$100

  • Broken glass: $200–$2,000

  • Sash, seal, or track repair: $200–$600

  • Latch or hardware issues: $75–$200

  • Broken window frame: $175–$1,000

  • Window screen replacement: $140–$480

Among the various entry points into your residence, it's crucial to recognize that your basement windows are arguably the most susceptible. Basements usually have windows facing the side and back yards, often concealed from driveway floodlights, porch lighting, and doorbell cameras. Their vulnerability underscores the importance of reinforcing basement window security to safeguard your home from break-ins.
