Your questions about fire rated sealant in Falmer
Do you work for landlords with property near Falmer station?

Is Falmer in your area for fire rated sealant?
Yes, Falmer is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
Do you carry out fire risk assessments?
No. That is for a fire risk assessor, designer or building control. We apply fire-rated sealant to the requirements they set.
Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Will it make a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Can new sealant go over the old?
No. The old sealant always comes out first.
Can you match the sealant colour?
In most cases you can choose. We will explain which colours are available and agree one before work begins.
Can you tell me how many minutes the seal will last?
We don’t issue ratings or certificates ourselves. The performance comes from the product’s tested details and the specification from your assessor or designer.
How we handle fire rated sealant in Falmer
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, so we follow the tested detail for each one. If you’re dealing with unsealed gaps around fire door frames and unsealed gaps where pipes and cables go through a wall, we can help, whatever the surface.
In a village or hamlet like Falmer, 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.
Whatever the size of the job, it’s backed by our 12-month guarantee.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Report cracked or damaged seals as soon as you notice them
- Store the list of sealed gaps with your building paperwork
- Never patch a fire seal with standard sealant
- Check whether a sealant can be painted before decorating over it
Let contractors know where fire stopping has been done, and make sure anything they disturb is resealed with a suitable product. A lot of damaged fire stopping comes from later work.
Open gaps do not only matter in a fire: they also let noise, draughts and sometimes pests through. Dealing with them early helps with all of these.
Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
What affects the quote in Falmer
We do not publish a price list, because jobs vary so much. The quote depends on:
- Whether old sealant or filler has to be cut out
- When we can work, for business premises
- Mould in or behind the old joints
- The size of the job
Combining jobs into one visit generally makes better use of the time than several visits. We will give you a clear quote for the lot.
Helping us quote
A few details help us give you an accurate quote. When you ask for a quote, tell us:
- Where the job is, and your postcode
- How many joints, rooms or windows are involved
- If it’s domestic, commercial or a hotel
- The problem you’ve noticed
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we will talk you through the work and give you a clear price.
What we do, step by step
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. It usually takes anything from a few hours to several days, depending on how many gaps there are. Somewhere like Falmer needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
Getting ready for the visit
- Keep children and pets away from the work area
- Move anything stored near the joints
- Tell us if parking is tricky

What else we do in Falmer
What we’re called out for in Falmer
If the sealant is too shallow, has the wrong backing or sits on a dusty surface, it is not installed as tested. Rushed fire stopping is common particularly when it was the last job before handover.
If you can see any of these, it’s time to have the joints looked at:
- Gaps flagged on a fire risk assessment
- New service routes left unsealed after building work
- Old fire sealant that has split or come away
- Open holes round services passing through fire walls
If you let a flat or house near Falmer station, any gap left by new services in shared walls should be closed with a fire-rated product.
Questions to ask before booking
- How long the guarantee is
- Who does the work, and how experienced they are
- Whether all the old sealant comes out first
- What preparation is included
What the job involves on each surface
Flats and HMOs
Working in occupied flats needs some planning. Access to flats and common areas is agreed in advance to keep disruption down.
Service penetrations
New gaps tend to show up where services have been added. We clean out what’s there and reseal to the right depth over any backing the detail calls for.
What fire rated sealant looks like in Falmer
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details.
For buildings such as The Parish Church of St Lawrence, gaps around pipes and cables are worth checking after any building work there. Schools such as Brighton Aldridge Community Academy are buildings too, and gaps opened by contractors for new cabling are a common finding in schools and offices.
