Durham, just outside Chico's city limits
Durham is an unincorporated community on the west side of Butte County, just south of Chico, where we're based as a masonry contractor, so we're down here regularly. It feels like part of town, but it sits outside any city's limits, and that changes a few things once a job needs paperwork.
What we find here is a mix. There are older homes close in, often with a brick chimney and fireplace that have a lot of years on them, and there are houses on bigger rural lots where the masonry is as much about the yard as the house. On the older houses the first thing I want to know is what's already there, what the brick is and what mortar it was laid in, because a repair has to match both or it won't last. On the bigger lots it's more about layout and access, like where a wall should run and how far we're carrying material to get there.
Working in Durham: what changes outside city limits
Because Durham isn't inside a city, building permits here come from the Butte County Building Division, not from Chico, and the county runs them through plan review and inspection under state and county codes, so a job that needs a permit has a review step before we start and an inspection along the way. The county doesn't issue business licenses in the unincorporated area, as its business licenses page explains, so the license worth checking on any mason you hire is the state contractor license through the Contractors State License Board. We're fully licensed and insured.
I find out which office covers your address before I write anything, and when the county needs a permit we take care of the paperwork as part of the job. The county's offices are over in Oroville, but applications, status checks and inspection requests all go through its online system, so nobody's driving back and forth. Price mostly comes down to what's behind the damage once we open it up, how closely new brick and mortar have to match the old, how high or hard to reach the work is, and whether a permit is involved. The schedule turns on that permit review and on what we find, and your written estimate spells out what's included so you can see where the money goes.
What do older Durham homes need most?
A lot of older Durham houses have a brick chimney and fireplace that have stood for decades, and the call usually starts with a stain on a ceiling or wall near the chimney. I don't go with the first guess on those, because a leak can get in at the crown, the joints or the flashing, which is the metal seal where the chimney meets the roof, and then show up somewhere else entirely. So I trace where the water actually travels before we price a fix.
Out on the bigger lots, the calls are about the yard, like a block wall along a fence line, a walkway out to the shop or a place to cook outside. That work is mostly about getting the footing and drainage right so the wall stays straight and the path stays level.

Masonry services for Durham homes
Chimney repair
Older Durham chimneys tend to leak at the crown and the joints first. Our chimney repair starts by finding where water actually gets in, then fixes that.
Tuckpointing
Mortar on older brick houses wears out before the brick does. We clean out worn joints and refill them with mortar soft enough to protect your original brick.
Brick repair
Cracked or spalled brick, where the face pops off, is common on older Durham houses. We replace damaged bricks with ones that match in size, color and texture.
Concrete block walls
Bigger Durham lots often need a wall along a property line or around a yard. We build them on solid footings and plan the drainage first.
Walkway construction
On rural Durham lots, the path out to a shop or garden is often still dirt. We build brick, stone or concrete walkways set where you actually walk.
Outdoor kitchen masonry
Bigger Durham yards leave room to cook outside. We build outdoor kitchen counters, grill surrounds and pizza ovens in brick, block or stone that suits your house.
How a Durham masonry job works with us
Call and describe the problem
Call (530) 399-1517 or send the form, and I'll ask a few questions about what you're seeing so I know what to look for. Then we set a time for me to come out to your place in Durham.
I find the real cause
I look at the brick, the mortar and where the water's going before I price anything, and it helps if you're home to show me where the trouble shows up inside. You get a written estimate that spells out what's included, and I tell you whether the county will want a permit.
We handle permits and work
If the county needs a permit, we file it and work starts once its plan review clears, so that review is usually what sets the start date. Our own crew does the job with me on site.
Walk the finished job together
When we're done, you and I walk the work so you can see the joints, the match and the cleanup before we call it finished, and any county inspection happens before then. The job is backed by our satisfaction guarantee.

Questions about masonry work in Durham
Can I pull my own building permit for masonry work in Durham, CA?
Yes, homeowners can apply for a building permit with the county over the internet, and so can licensed contractors, through the county's building page. The Building Division also takes calls at (530) 552-3699 if you want to ask about your job first. If you hire us, we take care of the permit paperwork as part of the job.
Do I need a permit to repair a brick chimney in Durham?
The county decides that, not us, so before work starts I check with the Building Division about your specific job. If it needs a permit, we file it and the work waits for the review, which is why I ask early instead of at the last minute.
Which building codes apply to a masonry permit in Durham right now?
Permit applications the county reviews now are checked against the 2025 building standards codes, along with the county's own codes. That matters if you had plans drawn up a while ago, because anything submitted since the end of 2025 is reviewed under the current codes, not the ones the plans were drawn to.
How much does masonry repair cost in Durham, CA?
Masonry repair in Durham is priced job by job, and I don't give a number until I've seen the brick, because the same crack can be a small repointing job or a sign of a bigger problem underneath. The biggest swing is usually repair versus rebuild, and when patching won't hold up I'll tell you straight. Your on-site estimate puts your own figure in writing.
What causes mortar to crumble on older brick houses in Durham?
Mostly age and water, because mortar is meant to be the softer part of a wall, so it wears first and over the years lets water into the joints. Old patches in hard modern mortar make it worse, since the brick ends up softer than the joint around it and starts cracking, and I saw good brick ruined that way on commercial jobs. We repoint with mortar matched to the original so the joint wears instead of the brick.
How long does a masonry repair take in Durham?
Most of the wait usually comes before we start, when a job needs a permit and the county's review has to clear first. Once we open up a wall or chimney, hidden damage can add work, and I'd rather show you what we found than guess at it up front.
