Long-Term Maintenance
Subject: What Long-Term Maintenance Actually Looks Like
Hi [First Name],
One of the most common questions we hear is “How much work is this going to be down the road?” The short answer: two afternoons a year and about $50 to $120 in materials. That is the real number for a properly built timber structure. Here is what that looks like.
01
What Maintenance Actually Involves
The problems people associate with wood — rot, warping, constant refinishing — come from poor design and deferred care, not from the material itself. A well-engineered timber structure needs one dedicated maintenance day per year, plus quick seasonal checks that take two to three minutes each.
- Clean — mild soap, soft brush, garden hose. Work top-down. About an hour.
- Inspect — check end grain, beam-to-post joints, hardware, and post bases.
- Protect — do a water-bead test on the finish. If water soaks in, it is time for a maintenance coat of stain.
Your structure ships with a shop-applied, UV-rated pigmented stain — two coats applied before shipping. The first maintenance coat typically goes on at 12 to 18 months, then every 2 to 3 years for most climates. South-facing or coastal structures may need it every 1 to 2 years.
We have structures that went three to ten years with no maintenance at all and came back solid — tight joints, plumb posts, zero rot. The stain had weathered and needed a refresh, but the structure itself was sound. That is what proper engineering buys you.
What Never to Do
Never use a pressure washer. High-pressure water strips stain, damages wood fibers, and drives moisture deep into the timber. A garden hose with a soft-bristled brush is all you need. Also avoid bleach, ammonia, steel wool, and metal brushes on stained surfaces.

Seasonal Care and Long-Term Value
| Season | What to Do |
|---|---|
| Spring | Full post-winter inspection. Clear debris from rafters. Check drainage paths around post bases. Trim vegetation. This is your primary maintenance day. |
| Summer | Quick walk-around. Watch for UV fading on south and west faces. Check for insect activity near post bases. |
| Fall | Second cleaning before winter. Clear leaves and debris. Reseal any deteriorated caulk at checks or joints. |
| Winter | Remove heavy snow above 6 to 8 inches with a soft brush — never a shovel. Keep drainage paths clear of ice. |
Surface checks — the small lengthwise cracks that appear as timber dries — are cosmetic, not structural. They typically stabilize within one to two years. Seal them with exterior-grade caulk and maintain at your annual inspection.
Over 20 years, a custom heavy timber structure costs $400 to $900 in total maintenance — stain, hardware, and repairs combined. A standard kit pergola runs $1,800 to $7,300+ over the same period, largely because of structural repairs that proper engineering prevents from the start.
We have done this over 7,000 times. The structures that last the longest are not the ones with the most maintenance — they are the ones that were engineered to need the least.
Your structure is designed to last decades with minimal effort. If you have questions about maintenance for your specific project — your climate, your exposure, your species selection — I am happy to walk you through it. We build for the long run, and we are here for every year of it.
