Westward Builders just finished a wonderful construction for a new studio on a hillside. A big part of the job was excavating the hillside and building a huge retaining wall. We did not even dream that it could go so smoothly and be so aesthetically p

Should You Check Your Foundation Before Remodeling?
Remodeling contractors often overlook the foundation, but this is a mistake. Before investing in a renovation, addition, or other major project, it’s critical to have a professional contractor (or a structural/soils engineer specializing in foundations) evaluate your home or building’s base.
Here’s why:
- Protect your investment – Remodeling on a compromised foundation can waste your hard-earned money.
- Increase your property’s value – A building with a compromised foundation is worth considerably less in today’s real estate market.
- Prevent future problems – Addressing issues now avoids costly and disruptive repairs later.
- Ensure safety – A level, stable foundation provides peace of mind.
Before you move ahead with your project, contact Westward Builders. We can give you confidence that your remodel or new build is being done on a solid foundation.
