Moisture management
What the scope should cover
Ask why the proposed product suits the existing masonry, what preparation is required and what defects it cannot fix. Product instructions, drying conditions and compatibility with earlier coatings affect the work.
What to keep after the visit
Keep the product name, treated area, preparation details and maintenance instructions. Separate any masonry repairs from treatment in the quote.
The question worth asking
“What has been ruled out before recommending treatment, and how does this product handle moisture?”
Ask for the answer in the written scope. If the work changes after access or inspection, request a revised scope and price before approving the additional work.
Prepare without taking risks
Tell the contractor about previous paint, sealers or treatments. Photograph interior stains before cosmetic restoration.
Confirm appointment access, who will be present and what records to have ready. Preparation does not mean dismantling the appliance, climbing the roof or reproducing a dangerous symptom.
Compare companies for this particular job
- Confirm experience with your chimney type and appliance model. A company that cleans masonry fireplaces may not service every gas or pellet appliance.
- Ask who performs the work, what credentials apply to that person and how you can verify them with the issuing organisation.
- Check current insurance and any local licensing or permit requirements directly. A profile badge is not proof of every qualification.
- Compare access, materials, diagnostic work, disposal, exclusions and follow-up. A lower total can represent a smaller scope.
