5 Steps to Pick the Right Spray Foam Insulation Contractor Around Houston
Houston’s heat and humidity don’t forgive sloppy insulation jobs. A rushed crew, cheap foam, or team that cuts corners can leave you with hot upstairs rooms, skyrocketing summer bills, clammy walls, or foam that sags in a couple years. We’ve seen it—and fixed plenty of it—at Phantom Foam.
Before you hand over your money, walk through these 5 steps. They’ll help you spot the real pros who actually care about doing the job right.
Step 1: Look for Real Houston Experience Not every contractor understands how our climate hits homes. Ask:
- How many years have you been spraying foam specifically in Greater Houston?
- Can you show recent jobs in neighborhoods like Katy, Cypress, The Woodlands, Spring, Sugar Land, Pearland, Conroe, Humble, Kingwood, or wherever you live?
- Do they talk about handling tight attics, crawl spaces, rim joists, and our humidity like they’ve done it hundreds of times?
If they’re vague or mostly talk about work in other states, move on.
Step 2: Ask How They Handle Safety for Crew & Your Family Good companies put safety first—both for the people doing the work and the people living in the house. Ask:
- What PPE do your installers wear? (Full-face respirators, Tyvek suits, etc.—not just basic masks.)
- How do you ventilate the space during spraying?
- What’s your family/pet evacuation plan and re-entry timeline? (24–48 hours is standard for safety.)
- Do you use containment (plastic sheeting, zip doors) to keep overspray out of living areas?
A pro will answer clearly and confidently. Hesitation or “we don’t need all that” is a red flag.
Step 3: Dig Into Foam Quality & Options Not all foam performs the same in Houston’s climate. Ask:
- Do you offer both open-cell and closed-cell? (Closed-cell is usually better here for humidity.)
- What brands do you use? (Look for names like Icynene, BASF, Demilec, Lapolla—avoid “generic” or no-name foam.)
- What thickness/R-value are you recommending and why?
- What’s the warranty on materials and workmanship? (10–20+ years is common for good companies.)
If they push one type for every house or dodge brand questions, walk away.
Step 4: Check Real Reviews & Talk to Past Customers Skip glossy one-line reviews. Look for:
- Recent, detailed feedback mentioning Houston-specific issues (attic heat, crawl space moisture, rim joists).
- Ask for 3–5 recent references in your area—actually call them.
- Scan Angi, Houzz, Google, or BBB for patterns (happy locals vs. complaints about mess, smell, or poor results).
Real pros have some 4-star reviews (nobody’s perfect) and customers willing to talk.
Step 5: Compare Quotes & Trust Your Gut Get at least 3 written estimates that spell out:
- Exact foam type and thickness (R-value)
- Square footage covered
- Prep work, containment, and cleanup details
- Timeline & crew size
- Total price (no vague “we’ll bill extra later”)
Then ask yourself:
- Did they listen to your needs?
- Were they on time and professional?
- Did they explain things clearly without pressure?
If someone feels pushy, vague, or suspiciously cheap, trust that instinct.
