Design And Build FAQ

Back to table of contents

How Can I Tell If My Windows Need Replacing?

If there are any cracks in your glass, this is a huge sign you need window replacement. In addition, if water leaks around the window or you feel a draft around the windows, it could be that they have aged out and need replacing.

Do I Need To Replace My Gutters If I Replace The Roof?

Not always. Replacing your gutters should be done when there is an issue or when you want to compliment your new roof.

Will New Siding Help My Home Be More Energy-Efficient?

Yes, it can. The new siding on the market is more insulating than what was installed years ago. If your siding is old, you could be losing a lot of your heating and air, resulting in higher energy bills every month.

Can You Help Me Decide On The Best Asphalt Color For My Roof?

Yes, we can. We are here to help you make any design decisions that you may need help with. And, we can lay out samples of what would complement your home’s color.

Is Steel Or Fiberglass Better For Entry Doors?

Both options have their positives and negatives. We can lay out the pros and cons of each entry door and show you the various styles so you can choose one that will fit in with the exterior of your house.
