What we do

Four services that cover most Oregon chimneys

Most of what goes wrong with a chimney here traces back to two things: creosote from burning softwood, and rain getting into masonry that is no longer sealed. These are the jobs that fix both.

A real sweep

What a proper sweep actually removes

The dark, tarry layer on the left is creosote. It is what is left behind when wood smoke cools on the way up a flue, and it is the fuel in a chimney fire. Oregon's softwoods and damp air make it build up faster here than in most of the country.

  • Rotary brushing of the full flue length, not just the accessible first few feet
  • Smoke chamber, smoke shelf and firebox cleaned, not only the liner
  • HEPA vacuum at the hearth and drop cloths over the floor throughout
  • Before-and-after photographs of your own flue, handed over on the day

Why United

No guesswork, no surprise invoices

Chimney work happens out of sight, on a roof, in a flue you cannot see up. That is exactly why so much of it gets oversold. Our answer is simple: photograph everything, explain it in plain language, and quote it before we start.

  • Every finding backed by a photograph you keep
  • A written price before work begins, not after
  • We will tell you when a chimney does not need work
  • Service in English and Spanish, start to finish

Oregon rain

Water is what actually destroys a chimney

Brick is a sponge. Through an Oregon winter it soaks up rain, then freezes, and every freeze pushes the masonry apart a little more. That is the cycle behind spalling brick, failing mortar, cracked crowns and the moss you can see on the left.

A breathable sealant stops rain going in while still letting trapped moisture escape. Done before the damage starts, it is one of the cheapest pieces of maintenance a homeowner here can buy.

How a visit runs

Four steps, no surprises

STEP 01

You call or book

Tell us what the chimney is doing. We give you a realistic window, usually within the same week.

STEP 02

We inspect

Camera up the flue, eyes on the crown, cap, flashing and firebox. Everything gets photographed.

STEP 03

You get a price

We walk you through the photos, explain what is urgent and what can wait, and put a number in writing.

STEP 04

We do the work

Floors covered, vacuum running, and a clean hearth when we leave. Then after photos so you can see it.

Inspections

You get the report, not just the verdict

An inspection is worth nothing if all you get is a technician's opinion and an invoice. Ours ends with a document: photographs of your flue, crown, cap, flashing and firebox, notes on what each one shows, and a clear separation between what is a safety problem now and what is simply worth watching.

  • Camera inspection of the flue interior
  • Structure, crown, cap and spark arrestor checked
  • Flashing and roof line inspected for water entry
  • Written recommendations, ranked by urgency

Questions

Straight answers

Once a year for a chimney in regular use. Oregon's long wet season and the resinous softwoods burned here build creosote faster than drier climates, so an annual sweep and inspection before the burning season is the standard recommendation.

No. Repair estimates are free and in writing. We show you photographs of what we found, explain the options, and give you a price before any work starts.

No. We run a HEPA vacuum at the firebox and lay drop cloths over the hearth and floor before the brush goes in. The fireplace should look the way it did when we arrived, only cleaner.

Water stains on the ceiling near the chimney, crumbling mortar, a cracked crown, rust on the damper or firebox, white chalky staining on the brick, or smoke pushing back into the room all point to repair work. Our inspection tells you which it is, with photos.

Yes. We serve customers in English and Spanish, and this entire website is available in Spanish. Call (503) 209-6590 and ask for service in Spanish.
