THE MODEL

Who You Are Actually Hiring

Most contractors send a salesperson to your first appointment and a project manager you have never met to run the job.

Spencer walks your property himself. He measures the setbacks, locates your panel and your sewer or septic connection, checks slope and drainage, and tells you what fits before anyone writes a number. He stays on your job through final inspection.

That is the whole model. One person, from the first site visit to the day the jurisdiction signs off.

OUR NUMBERS

Our Numbers

More than 350 completed projects.
Building in the Temecula Valley since 2004.

We publish these because specific numbers are checkable and vague claims are not. Any contractor can say "years of experience." Ask them how many projects and in what city.

WHAT WE BUILD

What We Build

ADUs

Including detached units, attached units, garage conversions, and junior ADUs. See our ADU guide.

Bathroom remodels

Including full remodels, walk-in shower conversions, and primary suites. See our bathroom work.

Room additions and lofts

Room additions and lofts. We also build decks, patios, and handle window and door replacement.

We do not do kitchens. Two services done properly beats six done adequately, and we would rather tell you that than take work we are not the best choice for.

FOCUS

Why We Only Do Two Things Well

Most general contractors take whatever comes through the door. We build ADUs and remodel bathrooms, plus the additions and lofts that sit close to that work.

That is a deliberate limit, and here is what it buys you.

We know what is behind your walls before we open them

Temecula and Murrieta housing is concentrated in a narrow build window. Most of it went up between 1990 and 2006. After a few hundred projects in those homes we can tell you what a 1990s tract bathroom will show us at demolition, and we price the contingency openly instead of hiding it.

We know every local permit counter

Each city in this valley runs its own review. Wine Country parcels split between city and county on the same road. A contractor who works one city and takes an occasional job elsewhere learns those the expensive way, on your project.

We turn down work we are not right for

We do not do kitchens. We say no to projects outside our service area. Telling you we are the wrong choice costs us a job and saves you a bad one.

EXPERIENCE

What 350 Projects Teaches You

Three things we do differently because of what went wrong on earlier jobs.

Check the panel before quoting

A full dwelling unit draws real load, and older homes here often run 100 or 125 amp service. Finding that out during rough electrical means a change order and a delay. Finding it out on the first site visit means a line item. Same cost, entirely different experience for the homeowner.

Test septic capacity before anyone pays for design

On septic properties in Wildomar and Wine Country, the county decides whether your system carries a second dwelling. That answer moves a budget more than any finish decision. Learning it after you have paid for plans is the worst sequence in this business.

Submit to the association before the city

In gated and HOA communities, architectural review comes first. Contractors who submit to the city first pay for a plan set, redesign the exterior after review, then resubmit. We have watched that sequence add four months to a build.

FAMILY RUN

What Family Run Actually Means Here

It is a phrase every contractor uses, so here is the concrete version.

The person who quotes your job is the person who runs it. There is no sales team working on commission and no rotating cast of project managers.

You get a direct phone number, not a ticket queue.

Our reputation in this valley is the only marketing that has ever worked for us. After 22 years in one area, a bad job follows you around the Costco parking lot. That is a stronger accountability mechanism than any contract clause.

CREDENTIALS

Licensing, Insurance, and How to Verify Us

California general contractor license B-842038, active and in good standing.

Bonded and insured. We carry general liability and workers compensation and provide certificates before work starts, not after you ask.

Every subcontractor on your job is licensed and insured. We do not put unlicensed labor on a residential site.

Check us before you hire us

Look up license B-842038 through the Contractors State License Board. The lookup shows the license status, the classification, the bond, and any complaint history.

Do this for every contractor bidding your project, not only for us. An unlicensed contractor leaves you personally liable for injuries on your property and gives you no recourse when work fails.

HOW WE QUOTE

How We Quote

Free consultation

We come to your property. In-home or virtual, whichever suits you. There is no charge and no obligation.

A written scope, not a headline number

You get a proposal with site work, permits, materials, and labor as separate lines. You see where every dollar goes and what is excluded.

We tell you what is not included

Site plan, city permit fees, school fees, and engineering consultants sit outside a construction number. So do soils reports, grading, retaining walls, HOA fees, and utility connection fees on the properties that need them. We say so in writing rather than discovering them in month three.

Change orders happen when you change your mind

Not because we skipped a site condition to win the bid. That distinction is the difference between a job that lands on budget and one that does not.

That covers Southwest Riverside County.

Working across five cities means knowing five permit processes. Temecula parcels near Wine Country sometimes fall under Riverside County instead of the city, and gated associations review before the city will issue anything. We have submitted in all of them.

As a plumbing contractor I've worked with a lot of builders over the past 25 years and the truly exceptional ones are few and far between. Woollard Construction is one of the best. We routinely go back to homes they've either remodeled or performed additions to years later for general plumbing maintenance or repairs and the homeowners still speak glowingly of their experience with Woollard construction even decades later. There is only ONE home builder I regularly recommend and that is Woollard Construction.
