Five Stars All Around

“They have a great team of professionals and did an excellent job installing windows on my home. Arrived on time, completed on schedule, and attention to detail is off the chart. They set up plastic sheets to cover all my furniture before they started and vacuumed and wiped the floor after completion, leaving no dust behind. Highly recommended!”

– D. Yu

I highly recommend them for all the services you may need. They were also the most reasonably priced of all the companies I contacted. Highly recommend!”

FAQs About Our Design & Build Services

Back To Table Of Contents

Q: Can Replacing My Siding Increase The Value Of My Home?

A: Yes, siding can increase the value of your home. Siding is one of the better projects to tackle when you are looking to increase curb appeal and value.

Q: How Long Does It Take To Replace A Roof?

A: The time it takes to replace a roof depends on the size. However, in most cases, you are looking at a day or two to complete. We can give you an exact time when we have evaluated your roof.

Q: How Can I Maintain My New Siding?

A: The siding we install is very low maintenance, so there will be little to do. However, we recommend that to maintain your siding, you spray it occasionally with a water hose to remove dirt while also watching out for the limbs and bushes near the siding. You will want to remove anything that gets too close to the vinyl to avoid damage.

Q: How Can I Choose The Perfect Patio Door?

A: Choosing the perfect patio door for your home depends on many factors. However, the first is your taste. We are happy to show you your choices and help you narrow down your options.
