House leveling requires more than correcting a visible slope. The work must account for the building’s load paths, foundation system, floor framing, surrounding soils, moisture exposure, and any previous structural changes.
Contact our experienced Bay Area team to discuss your home and arrange an evaluation.
The correct approach depends on why the home has moved, how its structure is supported, and whether the underlying condition remains active. Our House-Leveling Services may include one or more of the following elements.
Because every home responds differently, leveling must be completed in controlled stages. The objective is to improve support and alignment without placing unnecessary stress on finishes, framing, plumbing, or other building components. Request a free Estimate for your San Ramon property.
Structural changes rarely appear in the same way from one property to another. Some homes develop obvious slopes, while others show smaller changes around walls, floors, doors, or exterior surfaces.
These symptoms can have more than one possible explanation. A professional assessment is the best way to determine whether House Leveling or Structural Repair is appropriate.
Quality and service come first. We approach every job, big or small, with the same care and attention to detail we’d give our own homes. Our team combines time-tested building practices with modern innovation to deliver results that stand the test of time.

Mares & Dow Construction & Skylights installed a large Velux skylight for me in August 2017. The entire experience was wonderful and the skylight is beautiful, both functionally and aesthetically. Janet made sure the work was scheduled to be completed before a trip I had planned. Jimmy measured carefully when he quoted the work and even accommodated a last minute change on the location when he arrived to do the work. They protected my new floors and were careful to keep dust to a minimum. Archie came by to ensure that all was going smoothly. Freddy helped matched the stain on my nearly 70 year old tongue and grove ceiling that really took some effort and he even matched some a few small spots that a previous contractor had sanded and removed the original stain. EVERYONE was cheerful and knowledgeable. Now, my little mid century house has emerged into the light!
Mares & Dow Construction & Skylights replaced two aging skylights in our bedroom and installed automatic blinds on four skylights. This was not an easy job, since our bedroom has very very high cathedral ceilings. In fact, one other skylight installer refused to do the job altogether, and a second made a bid that was almost twice as expensive as Mares & Dow Construction & Skylights. Janet Mares, who was our main contact for the job, was a pleasure to work with. Her son, Jimmy, who led the installation, was fearless climbing the ceiling, and he eally knew his stuff. We’re thrilled with our new and improved skylights, and we appreciate Mares & Dow Construction & Skylights’ solid, reasonably priced, work. Thanks guys!
I’ve had Mares & Dow Construction & Skylights install 3 sun tunnels in my home and most recently, 2 skylights in my garage/art studio. I couldn’t be more satisfied with the quality of their work and professionalism! All my communications with their office and installers have been extremely pleasant. I would use them again (and again) and highly recommend them to anyone looking to install Velux skylights/sun tunnels in their home!
Being a new homeowner, i really did my research before having someone come out and give me a quote on a skylight. You never know what to believe when you read yelp reviews. So, i went ahead and had Jimmy from mares and dow come out and give me an estimate. He was right on time, came out and measured and was very professional while he was here. Janet called me a few days later and sent me over an estimate. I went them them and couldn’t be happier. It arrived in the time frame she had told me, and they were out that week. The workers came out on time, and were very friendly and professional. Dennis ( one of the owners) came out as well and checked on the job. The went above and beyond with their work. The skylight looks beautiful! Night and day from the old one. If you are wanting a skylight, i strongly reccomend going with mare and dow
We had Mares & Dow Construction & Skylights install a Velux skylight in our new master bathroom. The space was small and dark, so Mares & Dow Construction & Skylights suggested a big skylight to add in lots of natural light. They built in a double crown molding to beautifully frame the skylight, and now the space is open and airy with wonderful natural light. We can open the skylight during warm months to let in fresh air. It was a superb addition to our bathroom renovation and a great suggestion from Mares & Dow Construction & Skylights. They did a fantastic job and were great to work with! Thanks guys!

House leveling is the process of correcting and stabilizing portions of a home that have settled, sagged, shifted, or lost adequate support. The work may involve foundation components, crawlspace supports, beams, joists, or other structural elements.
Possible signs include sloping or dipping floors, sticking doors, misaligned windows, recurring cracks, gaps around trim, and visible changes in foundation or crawlspace supports. An evaluation is needed to determine the actual cause.
No. Unevenness may be related to foundation settlement, but it can also result from framing deflection, deteriorated supports, moisture damage, alterations, or variations from the original construction.
Not necessarily. The appropriate goal depends on the home’s age, condition, construction, finishes, and movement history. In some cases, improving support and reducing the slope safely may be more appropriate than attempting perfect levelness.
The timeline depends on the size of the affected area, accessibility, repair method, permit or engineering requirements, and whether related work is needed. A more reliable schedule can be provided after the property has been assessed.
Movement during leveling can affect rigid finishes such as drywall, plaster, tile, and trim. Controlled adjustments help manage stress, but some cosmetic repairs may still be needed afterward, particularly when substantial movement has occurred.
When water or soil moisture is contributing to settlement or deterioration, drainage improvements may be an important part of the overall solution. The order of work depends on the conditions present.
Some projects require engineered plans, structural calculations, or permits, while others may not. The project’s scope, structural system, and local requirements determine what is necessary.
Costs vary according to the cause and extent of movement, access beneath the home, repair materials, engineering needs, permits, and related foundation or framing work. An on-site evaluation is necessary for a meaningful estimate.
