Composite Isn't Maintenance-Free — It Just Needs Different Maintenance

One of the most persistent myths about composite decking is that it requires no upkeep. In reality, composite decks develop mold, algae, and surface staining — particularly in shaded areas and in Illinois's humid summer climate. They also need board and railing repairs over time.

The key is using the right methods. Standard pressure washing and cleaning products designed for wood can damage composite surfaces and void manufacturer warranties. We use composite-specific products and techniques that clean effectively without causing harm.

What Composite Deck Owners Are Saying

★★★★★

"My Trex deck had a serious black mold problem in the shaded area near the house. I tried consumer products twice with no real results. PerfectDecks used the right composite-specific treatment and the mold is completely gone. Two months later — still gone. They knew exactly what they were doing."

"Two Fiberon boards had cracked after a bad winter. PerfectDecks sourced matching boards from Fiberon's same color line, replaced just the two damaged boards, and it's completely unnoticeable. Clean and efficient — exactly what I needed."

FAQ

Composite Deck Questions Answered

Will professional cleaning void my composite deck warranty? ▼
Not when done correctly. Most composite manufacturers approve professional cleaning using their recommended products and methods. We use composite-safe products appropriate for each brand and won't damage the cap layer or void your warranty.
How often should composite decking be professionally cleaned? ▼
Most composite decks benefit from professional cleaning every 1–2 years. In Illinois's humid climate, shaded decks or decks near trees may develop mold and algae more quickly and benefit from annual cleaning. Preventive treatment after cleaning can extend the interval significantly.
Can you match replacement composite boards exactly? ▼
We do our best to match the brand, product line, and color as closely as possible. Exact matches are most achievable for boards from current production runs. We'll show you the available options before doing any replacement so you can approve the match.
Can you remove black mold from composite decking? ▼
Yes — and it's one of our most common composite services. We use targeted biocide treatments appropriate for composite surfaces that remove the mold and treat the surface to slow re-growth. Heavily shaded decks may benefit from annual preventive treatment.
Do you service all composite brands? ▼
Yes — we service Trex, Fiberon, TimberTech, Azek, Deckorators, Veranda, and all other major composite brands. If you're unsure of your brand, bring us out for an inspection and we'll identify it and recommend the right treatment approach.
