What that tells you
- Cost comes first. Variations on “how much” add up to more than any other question. If your site doesn’t talk about price, the homeowner gets the answer from someone else’s site, and calls them.
- They’re not sure what it is. “What is crawl space encapsulation” at 590 a month means many people heard the word from an inspector or a neighbor. Explain it in plain language: vapor barrier, sealed vents, drainage if needed, dehumidifier.
- They want to know if it’s worth it. Resale value, energy, smells, pests, mold. Answer honestly, including when it isn’t needed.
- Some will try DIY. “How to encapsulate a crawl space” is a real search. A page that explains what DIY gets wrong (drainage, sealing, dehumidifier sizing) brings you some of those people back when they get stuck.
The pages to build
- A cost page. What drives price: square footage, height, standing water, drainage, the dehumidifier, the condition of the walls. You don’t have to publish a number you can’t stand behind, but give ranges you’re comfortable with or explain what changes the quote.
- A “what is encapsulation” page. With photos from your own jobs, before and after.
- An “is it worth it” page. When you recommend it, when you don’t, and what happens if you wait.
- A dehumidifier page. “Crawl space dehumidifier” gets about 18,100 searches a month on its own.
- Town pages. For the towns where you want more encapsulation jobs, with jobs you’ve done there.
Each one links to the others and to your quote request. Together they cover the homeowner from first question to phone call.
