"Elvin is great. He fixed my wood double front doors and applied paint that I had picked out, as well as new handles/lock. He took his time, was very polite, and made sure everything was in order before in left. My front doors look amazing. Will be hiring him again for more work around the house. Also, his pricing was very reasonable and on point for the amount of repair and painting work he did."

"Was very nervous hiring someone to do my roof. I’ve had bad experiences in the past. The salesman Nick met me at my home. Gave me in full detail a step by step breakdown of how the project was going to unfold. I just got my deck done a month prior. He assured me that everything would be covered, and the clean up would be thorough. On the day of my installation, not only was property protected. The owners of the company Zak, and Rich came out personally to bring insulation board to cover my railings of my new deck. I was very impressed with that, the detail and follow through with everyone involved with the project. My wife and I are planning to get the roof done on our rental property this year, and I know I only need to make one call to get the job done right. I highly recommend A1 Home Improvement for any outdoor project you have."

"I hired Capital Construction to replace the aging roof shingles on my house. Their quote was completive with other local contractors and far less than national contractors. Their employees worked hard to make sure I was always informed on the status of the project. They took care to protect the house during the removal of the existing roof shingles. During installation of the new shingles the on-site crew responded quickly to my questions and concerns and resolved matters to my satisfaction. I would definitely hire them again."

Window Door Contractors FAQs, answered by experts

Window repairs cost $175 to $615, depending on the type of repair. Because double-hung windows have two sashes and multiple pieces of hardware, like locks and handles, there are many parts that can break over time. Repairing locks, latches, or other hardware costs about $75 to $200 and is easy to DIY. Fixing one or multiple sashes costs about $200 to $600.

Professionals clean window screens the same way a homeowner can—by removing the screens and cleaning them with a sponge. A window cleaning pro may come with better equipment, like a high powered wet/dry vacuum or pressure washer to speed up the process and achieve a deeper clean.

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.

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.

Some local utilities or state programs offer rebates or tax incentives for energy-efficient upgrades, including solar screens. Make sure to check with your local energy provider or government agency to see if you qualify for any cost-saving programs. Federal tax credits may also be available for qualifying window and exterior home upgrades.
