Fire rated sealant for homes and businesses in Bishop's Waltham
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. Which product suits a gap depends on its width, the materials either side and what runs through it, so we work to the manufacturer’s details. We work on door frames, plasterboard & masonry and pipe & cable gaps, and people most often call us about open joints along the top of partitions and seals cut through by electricians, plumbers or data installers.
Community buildings, schools and small businesses around places like Bishop's Waltham have washrooms and kitchens that see a lot of use. Their sealant and fire-rated joints are as important as those in any bigger building.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

How it works
On the day, we look over the joints with you first, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. Most jobs take a few hours for a handful of gaps, and longer for a whole building. For a job in Bishop's Waltham, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- We remove any old or unsuitable filler and clean the gap.
- 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.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
- Let us know if you’ve seen damp or leaks

How we quote for fire rated sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether old sealant or filler has to be cut out
- The product the joint needs
- How many rooms, windows or areas are involved
- The amount of work
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear price before any work starts.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- Photos by email, if that is easy
- The rough size of the job
- Whether it has been sealed before
- The type of property
There’s no standard price list, because every job is different. Instead, we send you a clear quote for your job. To arrange one, call 0345 464 0079 or drop us an email.
Landlord and commercial work in Bishop's Waltham
If you manage several properties in or around Bishop's Waltham, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs.
From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Allow for resealing whenever new services are run
- Ask every contractor to reseal any fire stopping they disturb
- Store the list of sealed gaps with your building paperwork
- Look in service cupboards and ceiling voids from time to time
Look at the sealed gaps as part of your routine walk-rounds. Watch for cracking, gaps or seals that have been disturbed and have them put right.
An open gap isn’t only a fire issue: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
What happens if it’s left?
Fire-rated sealants need more care than everyday sealant. How it’s installed changes how it performs, so we follow the maker’s details on every gap. In an older home around Bishop's Waltham, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Ask us for a quote and we’ll explain what it covers.

What fire rated sealant looks like in Bishop's Waltham
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you are given, installing the product to its tested details.
Community buildings like Church of St Peter are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. Rented homes near Botley station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
