"Contractor left a large paint sprayer in our garage for 4 months while the house was rented by vacationing guests. (the house is a vacation rental home.)  I had to point out to contractor that they painted over a fungus that was growing on house siding, instead of properly cleaning/removing this prior to painting.  They painted over the lights on the exterior of the house instead of removing prior to painting. Contract stated that soffit vents were to be installed on both sides of the house.  Contractor only installed soffit vents on one side of the house and did not inform me of this.  I paid contractor in full ($14,258.00) and found out later that the soffit vents were not installed on both sides of house.  December 7, 2015, I informed contractor I wanted him to install the missing soffit vents and needed the roof warranty paperwork.  Contractor told me he would send me the paperwork for the roof warranty. We still have not received the roof warranty. Jan 6, 2016 he responded to my request saying he would install the missing soffit vents, he still has not completed the work.  I have not heard from him since and have not received the roof warranty.  His phone has been disconected, voice mailboxes are full on other phone lines he has. We have texted, emailed and called he refuses to return any form of contact.  We have been forced to contact the roofing supplier ourselves in an attempt to obtain our rightfull warranty. We are not sure if they will be able to link the contractor to our roof. Plus our contract included a 10 year warranty on the workmanship and the company won't even respond to our requests to just finish the job they were paid for. I can only imagine trying to get them to stand by their workmanship warranty.

"Excellent service, very fast response to my request for service, picked up laptop, diagnosed issues. Initially thought it was an OS update issue but the hard drive had failed along with other components (including 'CPU). Because other components were involved, a new solid state hard drive was put into a laptop with a working processor - same type CPU as in the failed unit. The laptop was repaired and returned in less than a week. This company picked up and dropped off the laptop (driving from Huntsville, AL (about 60-70 minutes)-- great service in this covid environment. I would recommend this company to my family./friends and will use again."

"They've done good work. The quality is really good. Once they started the work it was done quickly, about two days. Rock solid and perfect clean up. Good technicians. They know exactly what they are doing. They give you a discount if you put a sign in your yard, the contract is put a sign up for a week a few times a year. They seemed to forgot to come get the sign a few times.

Window Door Contractors FAQs, answered by experts

Garage door screens can expand your living space, turning a garage into a home office, gym, or entertainment space. They provide comfortable ventilation, insect control, and privacy, allowing you to enjoy your space all year round. Consult a local garage door screen installer to add this feature to your space.

It’s possible to make minor screen repairs yourself using a waterproof adhesive for small tears or a screen patch kit for larger tears and holes. However, it’s usually a better option to call in a professional window technician. It’s very easy to use too much waterproof glue, resulting in a messy appearance that might demand a full replacement anyway. A screen repair technician will not only be able to carry out clean repairs and patches that aren’t obvious, but they can also let you know if replacing your screen is a more cost-effective option.

Installing a basement window generally takes a few hours, assuming there are no structural issues you need to resolve first. If you’re a novice DIYer, the project could take longer; on the flip side, a licensed and trained window contractor may be able to replace multiple basement windows in the time it takes a homeowner to replace one.

Yes, adding windows adds value to a brick house. Homeowners don’t shy away from more natural light and an opportunity to get fresh air. Adding a window is particularly beneficial if you live in an area with good weather for much of the year or if your home has a nice view. Keep in mind that many older brick homes have historic wood windows that add to the charm of the house. When you install a new window in a brick house, you’ll want to find one that matches the aesthetic of the existing windows.

While windows increase a home’s value, how much they increase it can vary. It depends on the age of the home and the type of windows. You can expect about 70% to 85% return on investment (ROI) when adding a window to your home.

For most common repairs, a professional window repair service can fix a window in one to three hours. However, replacing window frames or repairing a large, multi-pane window will likely take longer to complete. For comparison, a window installation or repair professional should be able to replace up to 15 windows per day.
