When to call us in Uxbridge
Movement in the structure can open gaps too: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
Most people get in touch after spotting something like this:
- Fire stopping disturbed by later work
- Gaps filled with a product that is not fire-rated
- Cracked or shrunken fire-rated sealant
- Open gaps behind door architraves
If you let a flat or house near West Drayton station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.
Questions to ask before booking
- Whether they’re fully insured
- Whether you can choose the colour
- How long to leave it before use
- How the surfaces are prepared before sealing
When something else is needed
Sealant is not the answer to every problem, and we’ll tell you before we start. It will not solve:
- Certifying a building or signing off its fire safety
- Big openings where sealant alone is not the tested solution
- Walls or floors that weren’t built to resist fire
If in doubt, phone 07833 053749 or email us and we’ll say what we think.

Why deal with it now?
Fire-rated sealants are less forgiving than ordinary ones. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Store the list of sealed gaps with your building paperwork
- Ask which product was used before you paint
- Take pictures of fire stopping before ceilings or boxing go back
- Include fire stopping when you schedule refits
Look at the sealed gaps as part of your routine walk-rounds. Look for cracks, gaps or sealant that has been cut or pulled out and get them seen to.
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.
How the job changes by surface
Service penetrations
New gaps tend to show up where services have been added. Old or unsuitable filler comes out before the right sealant goes in with backing where the detail needs it.
Plasterboard walls
We check that the board around the gap is sound. Loose material is removed so the sealant has a firm edge.
The process
At the end, we look at the finished work together. The work normally takes anything from a few hours to several days, depending on how many gaps there are, depending on the size of the job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Uxbridge. A visitor permit or a nearby bay makes the visit run more smoothly.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- Each gap is measured and its substrate and service noted.
- Any non-fire-rated filler is removed and the gap cleaned.
- We fit backing where needed and apply the fire-rated sealant to depth.
- We hand over a list of locations and products for your files.
How to prepare
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
