Permit – we submit via MBP, coordinate L&I electrical, and track comments so you don’t have to.

Protection + demo – dust walls, floor protection, negative air if needed.

Rough-ins – drains/ejector, vents, circuits, boxes to finish depth; moisture systems in place first.

Close-in + finishes – insulation, drywall, tile/trim/flooring, doors, lighting, paint.

Inspections + walkthrough – we schedule, meet the inspector, and fix small stuff on the spot. You get a punch list that actually closes.

We do full-scope basement renovation Edmonds work – from dry-out and sub-drain solutions to full finishes.

Moisture + structure first. We check for hydrostatic issues, existing drains/sumps, and vapor drive. Interior foam on foundation walls, correct furring, and sealed penetrations reduce damp spots and mold risk. (Best practice: non-water-sensitive foam against concrete so interior air can’t condense on cold walls.)

Layout + code. If you’re adding a finished basement guest suite Edmonds, we plan egress, clearances, and ceiling heights up front. Basements with sleeping rooms need emergency escape and rescue openings – and yes, window-well sizes matter. Habitable areas need 7' ceilings, with allowances for beams/ducts. We handle these checks in the drawings so there are no last-minute surprises.

Electrical + ventilation. We wire to the 2023 NEC and coordinate electrical permits with L&I. Bath fans and any new exhausts discharge outside – never into the attic or a joist bay. Range hoods for basement kitchenettes get ducted properly with terminations sized to code.

Plumbing where needed. Basement baths sometimes need sewage ejectors or a pump – sized and valved to the Uniform Plumbing Code sections used in WA. We follow the MyBuildingPermit rough-in checklist so inspectors see what they expect (ejector sizing, backwater valves, cleanouts).

Finishes that last. LVP or porcelain on decent substrates, foam-backed underlay where it helps, tile layouts that align with outlets and trim. Quiet doors, well-placed lighting, and storage that clears door swings. If you came here via basement finishing near me, this is the real work behind those nice photos.

Waterproofing options. If you’re already talking to a waterproofing firm, we’ll integrate their scope or bring our own – interior drains, sump, exterior drainage upgrades – then finish over a dry assembly.

Lighting & electrical – Lutron/Leviton controls; quiet, low-profile fixtures.

Plumbing – Kohler/Delta for serviceability; ejector equipment meeting UPC pump/discharge checklist.
