Foundation repair in Rancho Cucamonga CA - a repair planned before we dig

Cracks at window corners or doors that stick? We look with you, get an engineer's review and fix what's moving.

Do cracks and sticking doors mean my house needs foundation repair?

Foundation repair in Rancho Cucamonga is the work of steadying a house that has settled, cracked or heaved, and at P&J Rancho Cucamonga Concrete & Masonry it starts with a careful look at what your house is showing you before anyone picks a fix.

Most people call us because a door has started to stick, a window won't open or a crack has shown up in a wall, and they want to know if it's serious. I'd rather you understand what your house is doing before you spend anything on it, so I explain what I see as we go. Before we start, we check what the city asks for on your kind of job, and when a permit is needed we handle the application and line up the inspections.

The price turns on how much of the house has moved, what the reviewed repair plan calls for, how much digging it takes to reach the footing and how easy it is to get equipment to the wall, along with any crack repair afterward. The schedule depends mostly on the engineer's review, the city's permit side and the size of the repair. Your written estimate is where your own figure comes from.

What happens after you call us about your foundation?

It's the same three steps for every foundation job, and you'll know who you're dealing with at each one.

I come out and look at it myself

When you call or send a message, I'm the one who comes out to look at your house with you and answer your questions. I started this business in 2023, three years ago, after years of selling brick, block and stone to the masons in this area.

A written estimate you can read at home

After the visit I send you a written estimate, so you can see what the job involves and what moves its price before you decide anything. If something on it isn't clear, ask, because I'd rather answer one more question than leave you guessing.

City side first, then our crew on site

Once you say yes, we sort out the city side, then I run the work on site with our crew while an experienced mason leads any brick and stone work. We're licensed and insured. When we're done, we walk the finished job with you before we leave.

How we approach foundation repair

We start by looking at the stuck doors, windows and corner cracks with you, because together they show where the house has moved and where to look closer. Before we settle on a fix, we want an engineer to review the repair plan for your house, and one pier maker recommends the same thing, a registered professional engineer reviewing the final solution for each site. Once the plan is set, we dig out, carry out the repair it calls for, backfill and clean up.

Movement below often shows up in the brick above. When settling has cracked the mortar joints in a brick wall, tuckpointing replaces the worn mortar once the house underneath has been steadied, and a chimney that has cracked or pulled away can need its own chimney repair. If I see either during the visit, I'll point it out.

  • A look at your doors, windows and cracks, done with you
  • An engineer's review of the repair plan before the fix is chosen
  • Digging out where the plan needs access to the footing
  • The foundation support the reviewed plan calls for
  • Backfill and cleanup once the repair is in

How a foundation repair goes, step by step

Every house is a little different, but once the plan is reviewed most repairs run in this order.

  1. Get buried lines marked

    A helical pier guide has installers call 811, the national call-before-you-dig number, so buried utilities get marked with paint or flags before any digging. You're welcome to ask us about that call before the work starts.

  2. Dig down to the footing

    For outside work, one maker's guide digs down to the footing, either as a trench along the whole wall or as a hole at each pier location. Either way, the yard along that wall becomes part of the work area for a while, so it helps to move pots and patio furniture out of the way.

  3. Support the foundation

    Helical piles are one repair method for a foundation damaged by uneven settling, cracking or heaving, and one maker attaches them to the existing foundation to stop more settling or lift the house back to near its original condition. The engineer-reviewed plan decides what your house gets.

  4. Check the house and finish up

    One maker's guide ends the job by checking that doors and windows work, finishing crack repair and waterproofing, backfilling, cleaning up and taking final elevation readings, so ask me which of those are part of your job when I write the estimate. Satisfaction guaranteed.

Foundation repair questions from Rancho Cucamonga homeowners

What are the signs of foundation problems in my Rancho Cucamonga house?

Doors and windows that won't open and cracks in the walls are the usual signs of uneven settling. Cracks often spread from the corners of windows and doors, because that's where stress gathers, so those are the first spots to check. If you find them, take a few photos and give us a call.

Can we stay in the house during foundation repair?

Usually, yes. One helical pile maker says its piles go in with portable equipment, even in tight indoor spaces, and without vibration, so a household can keep using the house with little inconvenience. Outside, the yard along the wall being repaired stays part of the work area until it's backfilled.

How do I get a permit for foundation repair in Rancho Cucamonga?

Permits in Rancho Cucamonga come from the city's Building and Safety Department, and all applications are made online through its Online Permit Center. When your job needs a permit, we take care of that part for you.

How do I check if my house is in an earthquake hazard zone in California?

You can look up your address in the state's EQ Zapp tool, which shows whether it lies in a mapped earthquake hazard zone such as liquefaction, where soil temporarily turns to quicksand. It also says when the state's survey hasn't evaluated an area yet. If your address is in a zone, mention it when I come out.

Earthquakes, the city and where we work

Settling can leave a house weaker against wind or earthquake loads, and around Rancho Cucamonga that's part of why a crack at a door corner is worth a look. The California Geological Survey says new construction and significant remodels require site-specific geologic studies, which let builders steer clear of known hazards or build in protective features. Much of what we see here is brick and block, and movement below tends to show up there first.

We're based in Rancho Cucamonga and work across the cities around it, including Upland, Ontario, Fontana, Chino and more, so if your city isn't listed, ask us. If you have permit questions of your own, the city's building office takes technical ones by email at EDRnotification@CityofRC.us and quick ones by text at (909)488-4668.

Call about the cracks you're seeing

Cracks and sticking doors are easier to read before they're patched or painted over, so call (909) 360-4010 or use the contact form while they're still in plain sight.

If you're not sure whether what you're seeing is a foundation problem, call or write and I'll talk it through with you.
