Why it’s worth doing now in Gerrards Cross
Sealant isn’t the fix for every opening. Big openings, bundles of cables and plastic pipes may need batts, collars or wraps instead. We will say so if a gap needs something other than sealant. Around Gerrards Cross, 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.
A few things move the cost up or down: 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.

How we handle fire rated sealant in Gerrards Cross
Until it’s heated, intumescent sealant behaves like an ordinary sealant; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it. We work on linear gaps, pipe & cable gaps and plasterboard & masonry, and people most often call us about open joints along the top of partitions and new service routes left unsealed after building work.
In a smaller place like Gerrards Cross, commercial jobs tend to be smaller buildings: a pub, a surgery, a school, a shop or a few business units. Each needs the same care with its sealant as any larger building.
Whatever the size of the job, you get the same one-year guarantee.

What else we do in Gerrards Cross
Fire rated sealant around Gerrards Cross
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, and gaps around services are often picked up there. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. There are hotels and other places to stay in and around Gerrards Cross. For hotels, a room-by-room programme keeps most rooms in use while the work goes on.
Managing a site like The Gerrards Cross CofE School? Then fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as St James Church, service openings in its walls need the right fire-rated sealant, as in any building.

How the job changes by surface
Masonry and concrete
For masonry and concrete, we use a product tested in that substrate. We clean out dust and debris before sealing so the sealant bonds.
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
How it works
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the amount of work. For a job in Gerrards Cross, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since 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.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Getting ready for the visit
- Plan for the work area to be out of bounds to pets and children
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before

What we are called out for in Gerrards Cross
Sometimes the wrong product was used from the start: general-purpose foam, everyday silicone or caulk where a fire-rated seal was needed. It may look fine, but it isn’t a fire-rated seal.
Most people get in touch after spotting something like this:
- Open joints along the top of partitions
- Joints picked up in a fire-stopping survey
- Cracked or shrunken fire-rated sealant
- Gaps left after a refit or conversion
For landlords with property near Gerrards Cross station, any gap left by new services in shared walls should be closed with a fire-rated product.
What your quote should include
- Whether they’re fully insured
- Is VAT in the price?
- What the cure time is
- How the colour is chosen
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Include fire stopping when you schedule refits
- Never patch a fire seal with standard sealant
- Take pictures of fire stopping before ceilings or boxing go back
- Store the list of sealed gaps with your building paperwork
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.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the list grows.
