How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from a few hours to several days, depending on how many gaps there are and we leave things clean and tidy. A visit to Crawley Down is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- We plan the order of work and access, floor by floor or flat by flat.
- Old, damaged or unsuitable sealant is removed.
- Gaps are cleaned of dust and loose material.
- We apply and tool the sealant to the product’s tested detail.
- Locations and products are written up and any gaps unsuitable for sealant are flagged.
Getting ready for the visit
- Move anything stored near the joints
- Try not to wet indoor joints just before the visit
- Mention any parking rules near the property

Advice
Why deal with it now?
Doing it once, properly, beats doing it twice. If the details weren’t followed, the seal may need redoing when the building is next checked. Around Crawley Down, water from a failed joint in an older home can soak into timber and plaster, and that’s a much bigger job than renewing the sealant.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Fire rated sealant around Crawley Down
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
Rented homes near East Grinstead station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.

Local landmarks in Crawley Down
In Crawley Down, that means homes and buildings near Imberhorne School and the streets around them. The nearest railway station is East Grinstead station, about 2.5 miles east. Other landmarks nearby include Queen Victoria Hospital (3.5 miles east) and Effingham Park Motor Museum (1.4 miles north-west). Green spaces nearby include Hedgecourt Lake.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Crawley Down questions
I let a flat near East Grinstead station. Can you help?
Yes, landlords and agents are among the people we work for. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you cover smaller places like Crawley Down?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you tell me how many minutes the seal will last?
Ratings and certificates are not something we issue. What’s required is set by your assessor or designer, and the product’s tested details show what it achieves; we install to those details and record what we did.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is usually more efficient.
How much does fire rated sealant cost in Crawley Down?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Can you fill the gap behind a fire door frame?
Yes. The joint between frame and wall is sealed with a fire-rated sealant. The door leaf and its hardware need a door specialist.
What’s the difference between intumescent and fire-rated sealant?
Intumescent means it swells when heated to help seal the gap. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
When it isn’t the sealant
In fairness, there are a few things sealant won’t fix:
- Deciding what fire stopping a building needs
- Construction that doesn’t provide fire resistance on its own
- Certifying a building or signing off its fire safety
If you’re not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.

Common problems we fix in Crawley Down
Buildings are refitted and reconfigured over the years. A house turned into flats or an HMO, or an office split into smaller units, brings new walls, new service routes and new gaps.
Signs it’s time to call us include:
- Door frames with gaps between frame and wall
- Damaged fire sealant left by other trades
- Gaps around pipes and cables through fire-resisting walls
- Open joints along the top of partitions
If you look after a church, hall or community building such as All Saints Parish Church, gaps around pipes and cables are worth checking after any building work there.
