Wherwell Wood Fire Rated Sealant
We cover Wherwell Wood for intumescent and fire-rated sealant around gaps, frames and service penetrations. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Open joints along the top of partitions
- Holes left by a change of layout
- Fire seals that have cracked with movement
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Allow for resealing whenever new services are run
- Get damaged fire seals looked at promptly
- Check whether a sealant can be painted before decorating over it
Avoid covering a sealed gap with anything that isn’t part of the tested detail. If it needs repair, use the same type of product. We can tell you which product we used.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
About our fire rated sealant in Wherwell Wood
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. If you have ordinary sealant used where a fire-rated product was needed and sealant items on a fire risk assessment action list, we can help, whatever the surface.
In a village or hamlet like Wherwell Wood, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
All our work is covered by a 12-month guarantee, wherever you are in Hampshire.

- The problem you’ve noticed

The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of gaps, and longer for a whole building and we leave things clean and tidy. For a village or hamlet like Wherwell Wood, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We plan the order of work and access, floor by floor or flat by flat.
- We take out any damaged or unsuitable sealant.
- Dust and loose debris are cleaned from each gap.
- The fire-rated or intumescent sealant is applied and tooled to the tested detail.
- We record what was done and flag anything that needs a different system.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Tell us about any water getting in
- For business premises, tell us about site rules or sign-in

A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that is easy.
Advice
When to call us in Wherwell Wood
Gaps around door frames are easily missed. The architrave hides the gap between frame and wall, so it can be left open when a door is replaced.
The problems people generally mention when they call include:
- New service routes left unsealed after building work
- Open holes round services passing through fire walls
- Open joints along the top of partitions
- Seals cut through by electricians, plumbers or data installers
If you look after a church, hall or community building such as Church of St Peter, service openings in its walls need the right fire-rated sealant, as in any building.
What your quote should include
- Whether the sealant suits the joint
- How much experience the applicator has
- Whether they seal over old material or remove it
- How long the guarantee is
Common questions in Wherwell Wood
I let a flat near Andover station. Can you help?
Yes, rental work is part of what we do. Just ring 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear price.
Will you come out to Wherwell Wood?
Yes, Wherwell Wood is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Will we have a record of what was sealed?
Yes. We note each location and the product that went in, so you have it on file.
Can you work in occupied buildings?
Yes, whether the building is a school, an office, flats or an HMO, and whether it’s in use or not. Let us know the building’s hours and we’ll plan the work to suit.
Can you quote for more than one area?
Yes. Just list everything you need.
Do you take out the old sealant first?
Yes, every time. New silicone doesn’t stick to old silicone, so any old material comes out before anything new goes in.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we have been doing sealant work for more than 20 years.
Can you seal over the old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
When something else is needed
A few problems are outside what sealant work can do:
- Big openings where sealant alone is not the tested solution
- Construction that doesn’t provide fire resistance on its own
- Doors that aren’t fire doors in the first place
If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.
Joints and surfaces we work on
- Pipe & cable gaps
- Door frames

Why it’s worth doing now in Wherwell Wood
Squirting in whichever sealant is nearest doesn’t make a fire seal. A fire-rated product only performs as tested when it’s installed to its tested detail, so both the product and the method matter. Where a wall is exposed, as many are in small places like Wherwell Wood, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Why Wherwell Wood customers choose us
- Full insurance on every job
- Domestic, commercial and hotel work
- Sanitary silicone with an anti-fungal additive in wet areas
- We leave the area clean and tidy
