"We are extremely happy with A1 Home Improvement. We hired them to install siding on our home. From start to finish, wonderful staff to work with. Joe, our salesperson, spent a lot of time with us and even provided a 3D image of what our house would look like once completed. Tawana and Lisa promptly answered any questions brought to them. The installation team, Jose' and his crew were wonderful and did an excellent job. The guys that installed the gutters also did a great job. Our overall experience was excellent. Our home is just beautiful!"

"Jean was willing to meet with our unit owners to walk us through the project. He responded promptly to our questions and addressed any concerns that we had throughout the project. Jean and his crew did an amazing job on repairing the stucco on our building. They came early in the morning and worked hard to get the work done. This project was being done concurrently with another contractor working on our window installation. Jean was able to work around the major delays caused by the other contractor. He provided us with an updated schedule to ensure that everyone in the building was informed about the project process and the needs of the crew. I would recommend CT Stucco and would use them, if needed, in my own future home. The quality of their work was excellent."

Eifs Installers FAQs, answered by experts

Yes, you can always make an existing window bigger, but the job complexity varies widely depending on the location of the window and the framing around it. Exterior walls are always load-bearing, so making windows wider will require structural changes that make for a more complex but doable project. Making windows taller often won’t require structural changes.

Finding a reputable contractor for an egress window installation involves researching and vetting potential candidates. Start by searching for local professionals, reading customer reviews, and checking their websites for a portfolio of their work.

Once you have a shortlist, ask the following questions to ensure they are qualified:

• Are you licensed and insured?

• What experience do you have installing egress windows?

• Can you provide references from previous customers?

• Do you perform the work yourself or use subcontractors?

• What is the estimated project timeline and your current schedule?

• How do you handle payment?

Basements are generally required to have windows for your safety. At a minimum, windows should provide an egress in the event of a fire. But basement windows do more than offer a way out; basement windows also offer natural light and ventilation in an area of your home that is otherwise dark and musty.

A good U-factor for windows is 0.30 or lower, but they can range from 0.20 to 1.20. A general rule of thumb when it comes to the U-factor is that the lower, the better.

Most professionals can enlarge a window in five to 10 hours, depending on the window location, the exterior wall material, how easy it is to cut through it, and how much buildback you’ll need after the installation is complete. However, more complex projects can take two to three days from start to finish.
