How we handle fire rated sealant in Heckfield
We can work through a building room by room or floor by floor. It gives you a list to keep with the building’s fire safety documents. If you’re dealing with gaps where walls meet ceilings or slabs and door frames with gaps between frame and wall, we can help, on linear gaps, plasterboard & masonry and door frames alike.
If you have holiday lets, a converted barn used for business or a community building near Heckfield, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

What affects the cost of fire rated sealant
We do not publish a price list, because jobs vary so much. What we look at:
- Whether the work is at height
- The type of sealant required
- How much old sealant there is and how hard it is to remove
- The number and length of the joints
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts.
Asking for a quote
To help us quote quickly, please include:
- Any previous sealing or DIY work
- How we’d reach the joints
- A few photos by email, if you can
- The address or postcode of the job
Asking for a quote is easy: let us know the job and the location. A few photos by email make the job easier to understand.
What the job involves on each surface
Flats and HMOs
Working in occupied flats needs some planning. We agree access to each flat and the common parts before we start.
Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
How to look after the new joints
To keep the joints looking good and working properly:
- Make resealing part of every contractor’s brief
- Never patch a fire seal with standard sealant
- Include fire stopping when you schedule refits
- Photograph sealed gaps before they’re covered up
File the record of locations and products with your fire safety paperwork. It helps whoever checks the building next.
Small gaps around services are simple to deal with while there are only a few. Leave them and each new job adds another hole and the job gets bigger.
Honest limits
In fairness, there are a few things sealant will not fix:
- Issuing a fire rating or certificate for a building
- Construction that does not provide fire resistance on its own
- Large holes that need a different fire-stopping system
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

Heckfield questions
Is Heckfield within the area you cover?
Yes, Heckfield is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

Is intumescent sealant the same as fire-rated sealant?

Are you insured?
Yes. Mr Mastic is fully insured, with over 20 years’ experience in sealant work.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
Workplaces and buildings in Heckfield

Managing a site like Daneshill School? Then service openings in fire-resisting walls need checking after any refurbishment. For landlords with property near Mortimer station, any gap left by new services in shared walls should be closed with a fire-rated product.

What else we do in Heckfield
Do you need fire rated sealant in Heckfield?
Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.
It’s worth asking for a quote if you see:
- Gaps where walls meet ceilings or slabs
- Old fire sealant that has split or come away
- Unsealed gaps around fire door frames
- Open holes round services passing through fire walls
Community buildings like Church of St Michael are part of the picture too: gaps around pipes and cables are worth checking after any building work there.

The process
Good joint work is mostly preparation, and we don’t rush it. 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. Somewhere as small as Heckfield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- Locations and products are noted so you have them on file.
Getting ready for the visit
