What we know about Boulder
- Boulder County inspects its own electrical work and requires a separate utility sign-off on panel upgrades.
- The tree canopy on Mapleton and around Chautauqua fills gutters and roof valleys fast, so we clear before we inspect.
- A fair number of older homes still have knob-and-tube in the attic, which has to be dealt with before a panel upgrade.
How to pick the right concrete crew in Boulder
Concrete is the trade where failure shows up two winters later, so the price tells you almost nothing about how the slab will hold. The spec does. Here is what to compare before anything gets poured in Boulder.
- 01
A base spec, not just a thickness
Four inches of concrete on bare dirt will heave. Ask for the base depth, the gravel type and how it gets compacted, in lifts, with a machine.
- 02
A freeze-thaw mix with air entrainment
Colorado concrete needs entrained air and a sane water-cement ratio. Ask for the mix design in writing, including the PSI.
- 03
Control joints on a schedule
Joints cut to a plan, at the right spacing and depth, are what keep the slab from cracking where you can see it. No joint plan means no plan.
- 04
The permit when the work touches the right-of-way
A driveway approach, a sidewalk or anything inside the city easement usually needs one. Ask who pulls it before the forms go in.
- 05
Insured, with a reference from three winters ago
Any pour looks good in July. Ask to see a job from three winters back and go stand on it.
Ask every company these
- How deep is the base, and how is it compacted?
- What is the mix: PSI, air entrainment, water-cement ratio?
- Where are the joints, how far apart, and how deep?
- Does this need a right-of-way permit, and who pulls it?
- What is the reinforcement — mesh, rebar or fiber — and where does it sit in the slab?
- When can we walk on it and when can we drive on it, in writing?
Walk away if
- A price per square foot with no base spec behind it.
- No joint plan, and no answer when you ask.
- A pour scheduled the same week as the estimate, with no subgrade work quoted.
- Cash only, no contract, no insurance certificate.
What a real written quote includes
- Square footage and finished thickness
- Base depth, gravel type and compaction method
- Mix design: PSI, air entrainment, water-cement ratio
- Reinforcement type and where it sits
- Joint layout and spacing
- Permit fee if the work touches the right-of-way
- Finish, and whether the old concrete is hauled away
- Cure and traffic timeline, plus the warranty in writing
Every line above is something we hand you before we start, in writing. If a bid you get from us is missing one, hire the other company.
