Deck Specialists
Decks, porches, railings, and stairs are what we do every day. That focus shows in the details a general contractor would miss.
Licensed & Insured
CSLB #1151344, real insurance, and permits pulled with your local building department on every structural job.
Written Scope, Fixed Timeline
You see the plan, the price, and the schedule before work starts. Changes get priced before they happen, not after.
One Point of Contact
Moisés and his crew answer the phone, send progress updates, and walk the site with you at every milestone.
Detail-Driven Workmanship
Every cut, fastener, and transition handled with precision — because a deck lives outdoors where flaws show.
Walkthrough Before Payment
The last invoice comes after you've walked every board and signed off, never before.
How It Works
From first call to final walkthrough
A predictable four-step process, so you always know what happens next and who's responsible for it.
1
Free Consultation
We walk the space, listen to what you want, and flag anything that will affect scope, budget, or permits.
2
Written Estimate
An itemized estimate with materials, labor, and a real timeline. Free, and good for 30 days.
3
The Build
Our own crew does the work on the schedule we agreed to, with progress updates along the way.
4
Final Walkthrough
We walk the whole project together and fix anything on the punch list before the final invoice.

Built Durable. Backed in Writing.
A deck is a relationship, not a transaction. Every ISMA project is backed by a written workmanship warranty, and if something isn't right after we leave, we come back and make it right. That's the whole policy.
