Professional fire rated sealant in and around Clayhall, with every bit of old sealant taken out first and a 12-month guarantee.

How the job changes by surface
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.
Linear gaps
Linear gaps run along the head of walls, at floor edges and between panels. We seal them to the tested detail, with backing where it’s needed.
Fire rated sealant in Clayhall
Intumescent sealant looks much like any other sealant until it gets hot; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through, so we work to the manufacturer’s details. Common call-outs are for cracked or shrunken fire-rated sealant and open joints along the top of partitions, on pipe & cable gaps, linear gaps and service penetrations.
For a pub, café, guest house or shop in or near Clayhall, its washrooms and kitchen need the same sealant care as any big building, and fire-rated sealant around service openings should be restored after new pipes or cables go through.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

How it works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes from a few hours to a few days, depending on the number of gaps and the access. In a smaller place like Clayhall, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the faces cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products.
How to prepare
- Let us know about earlier repairs to the joints
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints

Looking after it afterwards
After the cure time, these simple habits help:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Get damaged fire seals looked at promptly
- Store the list of sealed gaps with your building paperwork
- Take pictures of fire stopping before ceilings or boxing go back
Tell other trades that the gaps have been sealed, and make sure anything they disturb is resealed with a suitable product. Later work is a common cause of damaged fire stopping.
A flagged gap shouldn’t wait for the next assessment. Have it sealed, then keep the record so you can show it was dealt with.

Why deal with it now?
Squirting in whichever sealant is nearest does not make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, which is why we match the product and the method to each gap. Around Clayhall, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.

How we quote for fire rated sealant
We quote each job individually. These are the things that affect it:
- Which sealant suits the joint
- When we can work, for business premises
- Mould in or behind the old joints
- The number of rooms or windows
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- The address or postcode of the job
- If someone has resealed it before
- Any access issues, like height or stairs
- Roughly how big the job is
Every job is quoted individually, so the first step is telling us about yours. Just ring 0345 464 0079 or email us with the details.
For landlords and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Letting agents and landlords in Clayhall can book us as well as householders. Resealing between tenancies keeps a property looking cared for.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Openings too large for sealant, which need batts, boards or another system
- Issuing a fire rating or certificate for a building
- Problems with the door itself rather than the gap around the frame
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before booking.

How much does fire rated sealant cost in Clayhall?

Can new sealant go over the old?

Do you provide details of the products used?
Yes. When the job is done, we give you the locations and products. Tell us if your assessor needs it in a particular format.
How long does the job take?
That depends on how much there is to do, but as a guide it takes anything from a few hours to several days, depending on how many gaps there are. We’ll tell you when we quote.
