"After they redid our counter tops and island, we had them paint out cabinets and build shelves up to the ceiling. The communication was on point this time and the results speak for themselves. Would definitely recommend them to anyone for any home project. "

"From start to finish, Enrique was professional, knowledgeable, and easy to work with. I've never felt better about investing in my home. Our front porch steps were severely in need of repair. The flagstone was falling off the frame and became a hazard for our family and others visiting our home. We had struggled to find others who could meet our budget or were comfortable taking the job. However, Enrique assured us this was well within his skill and experience and that we would be happy with the results. He could not have been more right! Enrique removed the old flagstone, added additional support for the existing frame, and installed beautiful new steps using Trex decking material. He even included exterior lighting! We are thrilled with our new stairs, and his work gives us great confidence in working again with MTZ Modern Carpentry. Thanks again, Enrique!"

Founded in 1989 by Dean Henninger, D.W. Henninger Construction has been recognized as a leading builder of custom homes and remodeling projects. Acting as a General Contractor, the entire Henninger team is known to exceed client expectations, leading to a steady stream of testimonials and referral clients.\n\nOver the past two decades, Henninger has managed projects in California: kitchens, bathrooms, room additions, entire home renovation, even complete construction of homes. Regardless of scope, Henninger approaches each project with the same foundation of principals: strong design aesthetics, comprehensive product options, sound project management, and a commitment to craftsmanship.\n\nDesign Aesthetics: With 20+ years of Bay Area experience, Henninger understands the many architectural quirks unique to Bay Area communities, making it easy to elaborate and integrate with established design aesthetics.\nProduct Options: Henninger is truly unique in being a single-source stop for design, remodeling, and product resources. Cabinetry, countertops, appliances, and plumbing fixtures are all available options for your project, and Henninger assists with selection, delivery, even vendor communication if there’s a problem.\nProject Management: Project management is essential to delivering a good customer experience. Henninger prioritizes project management to the same degree as design and crafting. Henninger is unique in using progress billing — a system that only charges for services following completion rather than pre-paying weeks or months before it starts.\nCraftsmanship: Henninger’s team of carpenters bring the best combination of experience and expertise to the table, but they offer much more than technical proficiency — by working with true craftsmen, Henninger projects balance design and functionality for maximum results on each and every project, regardless of scope.\nOur service areas: Oakland, Pleasanton, Livermore, Walnut Creek, Fremont, and surrounding cities. Projects in San Francisco and San Jose are also feasible — contact us for more information.

FAQs for basement remodeling projects in Ben Lomond, CA

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
