San Diego Masonry Contractor Building Walls, Patios & Chimneys to Code
Shaun Bagwell has laid block, stone and brick across San Diego County for more than 25 years, licensed under his own C-29 since 2012. Every wall, hearth and slab is built to California code — and Shaun is the one accountable for it.
The Contractor Who Answers the Phone Is the One Who Builds Your Wall
When you call (619) 581-2492, you reach Shaun Bagwell — not a call center, not a lead-reselling middleman, and not a rotating list of subcontractors. Shaun Bagwell Masonry is owner-operated. Shaun quotes the work, stands on the job, and puts his license number on the result.
That matters more than it sounds. The U.S. masonry market is worth roughly $40 billion, yet it is so fragmented that no single company holds more than 5% of it. Homeowners are effectively choosing one contractor at a time, with little brand to fall back on — which is exactly why a named, licensed, accountable owner is worth seeking out.
The need is real and local. San Diego County holds over 1.25 million housing units, and the median home sold here last year was 43 years old, with 71% of the county's homes now more than three decades old. Aging housing means cracked mortar joints, tired chimneys, leaning retaining walls, and foundations working against the region's notorious expansive clay. Shaun has repaired and rebuilt all of it — from coastal properties in Pacific Beach and Point Loma to hillside lots in El Cajon, Alpine and San Carlos.

A California C-29 Masonry Contractor license covers concrete units, baked clay products, concrete and clay block, natural and manufactured stone, terra cotta, and fire brick. Here is what Shaun does with it.
01
Retaining Walls & Structural Masonry
San Diego's hillside lots and expansive clay make retaining walls the county's most safety-critical masonry job. Shaun builds CMU, segmental, poured-concrete and natural-stone walls sized to the lateral load each site actually carries. San Diego code requires engineered plans and a permit for any retaining wall over roughly three to four feet — and more so where a driveway, slope or structure adds surcharge. Drainage is where most walls fail: perforated pipe in angular gravel backfill, never native clay. Budget roughly $30–$120 per sq. face ft. depending on height, type and engineering.
02
Block Walls & Property-Line Fencing
CMU block walls define most San Diego property lines. Shaun builds privacy walls, sound walls and boundary walls with grouted, steel-reinforced cells and your choice of finish — stucco, split-face, slump stone or stone veneer. Every wall meets California Building Code Section 2104 for reinforcement spacing and mortar type, which is non-negotiable in Seismic Design Category D.
03
Foundation Repair & Concrete
San Diego's clay swells when wet and shrinks when dry, and that cycle drives cracking, settlement and upheaval — especially on older cut-and-fill lots poured before modern compaction standards. Shaun's foundation repair fixes the cause, not the symptom, and he pours concrete slabs, footings and flatwork — including driveways — with correct mix, reinforcement, joint spacing and cure time.
04
Fireplaces & Chimneys
A masonry fireplace or chimney in San Diego has to satisfy Chapter 10 of the California Residential Code and Seismic Design Category D reinforcement: rebar ties, correctly sized flue liner, a capped crown with a drip edge, and a footing at least 12 inches thick extending 6 inches past the foundation on every side. Shaun builds new hearths as a fireplace specialist and handles chimney repair — crown, repointing, flashing and liner. Note that California will not let you patch and reuse a cracked masonry chimney; it must be removed and rebuilt to current seismic standards, under permit.
05
Patios, Pavers & Outdoor Living
With about 266 days of sunshine a year, outdoor space is among the highest-return work you can do to a San Diego home. Shaun installs patios in concrete, flagstone, travertine and brick; sets pavers in interlocking concrete, clay and natural stone over a properly compacted base with edge restraints that stop shifting; and builds slip-resistant pool decks with the drainage slope San Diego's heavy-rain days demand. Most hardscape runs $18–$40 per sq. ft. by material and complexity.
06
Stone & Brick Veneer
Stone earns its keep at resale. The 2025 Zonda Cost vs. Value Report puts manufactured stone veneer at a 208% return — the third-highest ROI of any improvement in the country. Shaun installs full facades, column wraps and veneer, and matches mortar color and stone texture on repairs so new work disappears into old — across Spanish Colonial, Mediterranean and modern elevations alike. See the gallery.
07
Repair & Restoration
The bread-and-butter repairs Shaun runs weekly: repointing failed mortar, swapping cracked or spalled brick and stone, crown and flashing work, structural crack stabilization, and stopping water intrusion at its source. Salt-air properties in La Jolla, Del Mar, Pacific Beach and Point Loma deteriorate faster, and Shaun diagnoses whether the culprit is moisture, soil, seismic movement or age before quoting a fix.
08
Commercial Masonry
For property managers, GCs and business owners, Shaun handles facade work, structural block, storefront hardscape, ADA-compliant walkways and tenant improvements — phased to keep the doors open and the schedule intact.
A homeowner needed a 40-plus-foot retaining wall to hold a sloping back yard. Shaun engineered it to code, detailed the drainage to keep hydrostatic pressure off the stem, and finished it clean. In the client's words, the work came in at a fair price with "a very high quality of workmanship."
Paver Installation — Referred by a Pool Builder
A San Diego pool contractor brought Shaun in to set the pavers on one of his job sites. Compacted base, tight joints, correct edge restraint — the kind of surface that stays flat after the first wet winter. The builder says he'll keep using Shaun: "he did a great job… very fair on his prices."
Four San Diego Realities That Decide Whether Masonry Lasts
Out-of-area contractors underestimate these constantly. Getting them right is the difference between masonry that lasts decades and masonry that fails in a few winters.
01Expansive Clay and Foundation Stress
Per the San Diego County General Plan EIR, highly expansive soils sit predominantly in the coastal plains, dissected marine terraces and uplands — right where most of the county's homes are built. That clay swells with rain, irrigation or a plumbing leak and contracts through the long dry season, and the cycle loads foundations, retaining walls, slabs and any in-ground masonry with real force. Homes built before the 1970s–80s — nearly 40% of the county's stock — often sit on cut-and-fill lots poured without modern compaction, which makes them prone to settlement and wall failure. Shaun builds to local geotechnical guidance, with engineered footings and gravel-backfilled drainage — and never backfills a wall with native clay, the single most common cause of the failures he's called out to fix.
02Coastal Salt Air and Material Breakdown
San Diego's 70 miles of coastline push salt-laden air through Pacific Beach, Point Loma, Ocean Beach, La Jolla, Del Mar and Mission Valley. Airborne salt works into mortar joints, concrete and the pores of natural stone, accelerating efflorescence, spalling and corrosion of embedded steel. Coastal work calls for higher-bond, moisture-resistant mortar (Type S or Type M), corrosion-resistant ties and anchors, and sealing on schedule. Inland — Kearny Mesa, Tierrasanta, El Cajon, Alpine — the enemy is temperature swing and different soil, not salt. Same county, different material spec.
03Seismic Design Category D
San Diego sits in Seismic Design Category D, among the highest seismic classifications in California, and it dictates how everything gets reinforced:
Retaining walls — reinforcement spacing and grouting to CBC Section 2104 for seismic loading.
Chimneys and fireplaces — vertical and horizontal rebar, anchored to the structural frame at floor and roof.
Block walls — grouted, reinforced cells at set intervals to take lateral force.
Foundations — compliance with Chapter 18 (Soils and Foundations) of the San Diego Building Code, including expansive-soil and seismic load provisions.
The City of San Diego has enforced its Unreinforced Masonry (URM) Ordinance hard for decades, requiring owners to retrofit or demolish buildings with unreinforced masonry bearing walls — and state law makes any un-retrofitted URM building in seismic zone 4 post visible earthquake-warning signage. Shaun treats seismic reinforcement as mandatory on every job, not an upsell.
04East County Fire Country and Noncombustible Masonry
Shaun works out of Alpine, in the East County foothills where wildfire is a design input, not a footnote. Masonry is noncombustible by nature, which is why block and stone walls, veneer and hardscape are among the most effective defensible-space materials around a home in a Wildland-Urban Interface zone. San Diego County requires that fencing within five feet of a structure in a fire hazard zone be noncombustible or an approved fire-retardant material — a spot where a CMU or stone wall does double duty as privacy and fire protection. In Alpine, El Cajon, Lakeside and the rest of the back country, that's a reason homeowners choose masonry over wood.

Why the spend pays back:
The 2025 Zonda Cost vs. Value Report found manufactured stone veneer returns 208% at resale — third-highest of any home improvement — and eight of the top ten resale projects were exterior work. San Diego context sharpens that math: the county issued 11,572 housing permits in 2024, the median home sits near $900,000, and local build costs run 5–10% above national averages thanks to California code, a skilled-labor shortage (trade wages climbing 6–8% a year, with an estimated 349,000 new construction workers needed nationally in 2026) and material logistics. Against a $900K home, a failed retaining wall can cost $40,000+ to rebuild and stall a sale — so doing masonry right the first time is the cheaper number.

What San Diego Clients Say About Shaun
EXCELLENTBased on 11 reviews
In searching for a company to build a 40+ ft. retaing wall for my back yard, cost (although important) is not my highest priority. In these times that we find ourselves living in, honesty and integrity seem to be in short supply. When I met Shaun Bagwell I was pleasantly surprised to find these human qualities alive and well. He not only gave me a fair price (although a bit higher than pre-covid), but he proved himself to be highly professional, courteous, respectful, and honest, along with a very high quality of workmanship on my wall. I would not hesitate for one moment to give my highest recommendation to anyone looking for someone to do any type of masonry work as described on his website. Thank you Shaun Bagwell.

(salt-air resistance, coastal setbacks, Coastal Development Permits)
Yes. Shaun comes to the property, assesses the scope, and leaves you a written, itemized proposal at no cost and no obligation. Call (619) 581-2492 or request one online.
Are you licensed, bonded and insured?
Yes — active California C-29 Masonry Contractor license through the CSLB, a $25,000 contractor bond, plus general liability insurance. You can confirm it yourself in 30 seconds at cslb.ca.gov by searching license #979389 — check that the status reads "active" and the classification shows C-29.
Do I need a permit for my project?
It depends. The City of San Diego requires a permit for masonry fireplaces, wood-burning prefab fireplaces, retaining walls over about 3–4 ft (especially with surcharge) and most structural masonry. Cosmetic repairs, low garden walls and some paver work often don't. Shaun flags what yours needs at the estimate and pulls the permit when it's required.
How long will the work take?
Small repairs and repointing: one to three days. A new patio or paver install: one to two weeks. Retaining walls, fireplaces and structural work: two to six weeks with engineering and permits. Your proposal gives you a specific timeline.
What is Seismic Design Category D and why does it matter?
It's one of California's highest earthquake-risk classifications, and San Diego is in it. It governs how chimneys, retaining walls, block walls and foundations must be reinforced — steel, anchor ties, proper grouting. Every masonry job Shaun builds meets current CBC seismic requirements.
Do you work in both stone and brick?
Yes — natural stone, manufactured stone veneer, clay brick, CMU block, flagstone, travertine, granite and slate, with mortar color and texture matched for invisible repairs.
How does San Diego's climate affect masonry?
Coastal salt air corrodes mortar, concrete and embedded steel; inland heat swings and expansive clay stress foundations, walls and slabs. Shaun matches materials and methods to your property's specific microclimate rather than using one spec county-wide.
What areas do you serve?
All of San Diego County — San Diego, Chula Vista, La Jolla, El Cajon, Pacific Beach, Point Loma, Mission Valley, Kearny Mesa, Tierrasanta, San Carlos, Alpine, Santee, Lakeside, National City, Del Mar, Solana Beach, Rancho Bernardo, Escondido, Carlsbad, Oceanside and beyond — plus select areas of Riverside and Orange County.
How do I verify Shaun's license before hiring?
Go to cslb.ca.gov, choose "Check a License," and enter #979389. You'll see the license status, C-29 classification, bond and workers' comp status. Verifying any masonry contractor this way before signing is smart — California requires a C-29 for masonry work over $500 in combined labor and materials.
Can you work with my HOA or handle permit approvals?
Yes. Shaun regularly builds to HOA design requirements and handles the City or County permit process — engineering coordination included — so approvals don't stall your project.
What makes a masonry quote go up or down?
Wall height and engineering, material (CMU vs. natural stone vs. veneer), site access and slope, drainage requirements, whether a permit and engineered plans are needed, and soil conditions. That's why Shaun quotes on-site rather than sight-unseen — the property decides the number.
Ready to Get It Built Right?
Whether it's a retaining wall engineered for San Diego's clay, a chimney rebuilt to current earthquake code, a stone patio that turns the back yard into a room, or a mortar repair that keeps water out of your walls — Shaun Bagwell handles it personally, start to finish.
Free on-site estimate, a clear written proposal, and a workmanship guarantee on every job. Call (619) 581-2492 or send a message — Shaun responds within one business day.
