Spray Foam Cold Calls: How to Spot a Hard Sell

How the pitch usually runs

Cold callers selling spray foam use a handful of familiar approaches. One is the free inspection or free survey, where someone arrives to look at your loft and finds problems that only their product can fix. Another is the grant or scheme pitch, claiming that government funding is available if you sign up now. A third is the scare: your roof is leaking heat, your tiles are about to slip or your insulation is out of date. A fourth is the discount that ends today. In all of these, the aim is to get a signature before you have time to think or compare.

There is also a version by phone or text. A caller says they are working in your street, that a neighbour has already had it done, or that they are checking eligibility for a scheme. Treat all of it as marketing until proved otherwise. Our page on spray foam mis-selling describes what went wrong for many households.

Red flags to watch for

Pressure to sign on the day. A genuine quote is valid for a reasonable period, and anyone insisting that the price disappears tonight is applying pressure. No written quote or specification, only a verbal estimate or a figure on a phone screen. Vague answers about the product, thickness and ventilation. Claims that foam will cure damp, replace the need for a survey or increase the value of your home, none of which can be promised. A request for a deposit in cash, or for payment in advance of any work. No company address you can check, and a name that changes from one call to the next.

Be especially cautious if the caller says your existing loft needs foam urgently, because the RICS consumer guide sets out real downsides: damp can be sealed in against the timber, the roof is harder to inspect, and when homes are sold or remortgaged the foam can cause delays. A salesperson who does not mention any of this is not giving you the full picture.

Another tactic is to claim that your loft insulation is illegal, out of date or no longer meets the rules. Nothing obliges you to replace a sound loft quilt with foam, and nobody can force you to insulate to a higher standard because of a doorstep visit. Likewise, a promise that the foam will pay for itself in savings within a short period should be treated as unproven, since savings depend on the house and no honest salesperson can state them without looking at your bills.

Grants deserve extra care. Genuine schemes are run through official channels and assessed by application, not offered by a caller who needs your signature today. If you think you might qualify for support, look up the scheme yourself on a government website and apply through it.

Questions that cut through it

Ask who they are and where they are based, and write it down. Ask what product will be used, at what thickness, and for what price per square metre. Ask how the roof will be checked first for leaks and damp. Ask what the guarantee covers, who stands behind it if the company closes, and what the ventilation plan is. Ask for it all in writing, and say you will decide after taking advice. A firm that cannot answer clearly, or gets annoyed, has told you what you need to know.

You can also compare with another source. Have a roofer, not an insulation salesperson, look at the loft, since we have no foam to sell and no reason to recommend it. We survey for free, photograph what we find and tell you if your roof is fine as it is. Our guide to spray foam roof surveys explains what a proper check involves.

Keep a log if you receive repeated calls: date, time, number, company name and what was claimed. Register your number with the telephone preference service and ask callers to remove you from their list. Do not press buttons on recorded messages, and do not confirm personal details. Being polite and brief works, and so does simply hanging up.

If you have already signed or paid

Do not panic. Read the contract for a cancellation right, since some doorstep and distance sales carry one, and check the dates. Citizens Advice can explain consumer rights in plain language, and Trading Standards deals with unfair selling. Keep every document, and do not let work begin if you are still unsure. If foam has been fitted and you now have doubts, ask for an independent survey of the roof and the timbers, which will tell you the facts.

If it turns out the foam needs to come out, our spray foam removal page explains the process, and the wider service is on the spray foam hub.
