Seal your home in September — why the timing matters
September is the best window to schedule exterior sealing and small repairs in the South Okanagan: daytime temperatures are cooling from peak summer, humidity tends to be lower, and there’s typically enough dry weather for sealants to penetrate and cure properly — which improves durability and lifespan.
As local contractors (not inspectors), we’ll visit your property, show you what should be prioritised, and provide a free on-site quote for September scheduling.
The real risks of leaving seals and finishes unattended
Minor gaps and failing finishes aren’t just cosmetic. When wood, caulking or flashings fail:
Water gets in → trapped moisture causes rot and mould growth. Mould in homes is linked to respiratory symptoms and should be addressed quickly. Teak & Deck ProfessionalsCanada.ca
Pests move in → damp or decayed wood attracts carpenter ants and other wood-nesting pests that create structural damage and expensive remediation needs. University of Minnesota Extension
Small jobs become big bills → a plank, a trim piece or re-caulking now can avoid full board, cladding or structural replacements later.
These are the precise problems real buyers and home inspectors look for — which is why targeted, documented pre-listing work often returns more than it costs.
What we check
(practical, on-site checklist)
When we come for your free quote we look at the most common failure points that cause the issues above:
Deck boards & railings — hairline cracks, fastener corrosion, loose boards.
Exterior siding & trim — failed caulking, exposed seams, soft spots behind cladding.
Windows & doors — broken seals, perished jamb caulk, rot at sills.
Roof flashings & chimney seals — small leaks that can cause attic mould.
Soffits, eaves & fascia — hidden rot that invites pests.
Foundation penetrations & grading — water pooling at foundations leads to damp basements.
Garage doors, vents & exterior vents — gaps that let moisture and pests in.
Exterior finish film (paint/stain/UV sealer) — where film breaks down, wood is exposed to accelerated decay.
We’ll photograph problem areas, explain priority vs nice-to-have items and give clear cost ranges on-site.
Typical cost logic (what to tell sellers & buyers)
Small fixes & re-caulking: usually a few hundred dollars.
Board replacement / flashing repairs: commonly low thousands depending on scope.
Large remediation (extensive rot / structural repairs / pest remediation): significantly higher once multiple trades or remediation steps are required.
A targeted September seal and small repairs are often the highest ROI move for sellers — they reduce negotiation risk and help the property present better on market.
Pre-listing package for realtors
(how we help you move the sale)
We offer a realtor-friendly pre-listing bundle tailored to the South Okanagan:
Free on-site visit & written quote (September priority slots).
Targeted repairs + sealing package (examples: deck + 3 exterior re-seal points, or siding + window reseal package) at transparent flat rates.
Before/after photos and a one-page maintenance note for listing disclosures and buyer packs.
Workmanship note/invoice to support offers and reduce buyer concerns.
This removes friction for agents and buyers and speeds closings by dealing with common exterior concerns up front.
How to prepare before we arrive
Clear access to decks and exterior walls.
Note any known problem spots (drafts, stains, visible rot).
If possible, have the realtor or seller available for a 10-minute walk around to prioritize work that will help the sale.

FAQ
Q: Will caulking and sealing always fix the issue?
A: Sealing and re-caulking prevent future moisture intrusion. Small rot can be repaired as part of a targeted job; extensive rot or structural damage will require a separate remediation quote.
Q: Do you provide paperwork realtors can use?
A: Yes — we supply before/after photos, a written invoice and a short workmanship note suitable for listings.
