Fire rated sealant in Polstead Heath
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then apply it to the depth its tested detail calls for. If you are dealing with unsealed gaps around fire door frames and gaps left after a refit or conversion, we can put it right, on door frames, linear gaps and flats & HMOs alike.
For a small place like Polstead Heath, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.
A one-year guarantee comes as standard.

How the job changes by surface
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. The sealant is chosen for what passes through and how wide the gap is.
Door frames
The gap between a door frame and the wall around it needs sealing as well as the door itself. We seal that gap with a fire-rated sealant suited to the frame and wall.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Tell trades working in the building that fire seals must be put back
- Photograph sealed gaps before they’re covered up
- File the fire-stopping record where your assessor can find it
- Allow for resealing whenever new services are run
Any fire seal that’s cut or drilled needs resealing to its tested detail. If you need new services through a sealed wall, plan the fire stopping as part of the job.
Open gaps don’t only matter in a fire: noise, draughts and even pests can come through too. Sealing them early helps on every front.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Walls or floors that weren’t built to resist fire
- Big openings where sealant alone is not the tested solution
- Sign-off of the building, which sits with building control or your assessor
If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
How the visit works
You do not need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for a handful of gaps, and longer for a whole building for a typical job. In a small place like Polstead Heath, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Preparing for the visit
- Let us know about parking restrictions
- On commercial sites, let us know about site rules
- Tell us about access, such as stairs, a lift or high-level joints

Is there a guarantee on fire rated sealant in Polstead Heath?

Do you remove the old sealant?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Can you tell me how many minutes the seal will last?
Ratings and certification sit with the product’s test evidence and whoever specified the work. We apply the specified product to the manufacturer’s details and giving you a record of where it went.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. We cover Polstead Heath and the rest of Essex.
Is intumescent sealant the same as fire-rated sealant?
Fire-rated is the broad term for sealants tested for fire stopping. Intumescent types expand when heated, and they’re one of the options. We use whichever the specification and tested details call for.
How long will you be here?
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 give you a better idea when we quote.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
