Fire rated sealant around Guildford
Guildford has hotels and guest accommodation in and around it. For hotels, a room-by-room programme keeps most rooms in use while the work goes on. 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, which is often where open fire-stopping gaps are first noticed. We work to the specification you are given, installing the product to its tested details.
If you let a flat or house near London Road (Guildford) station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. If you look after a church, hall or community building such as Church of St John the Evangelist, older buildings that have had new heating or wiring often have service gaps worth checking. Schools such as Sandfield Primary School are buildings too, and fire-stopping around service openings should be restored whenever new services go in.
Guildford is about 27 miles south-west of London, in Surrey. We provide fire rated sealant to householders, landlords and businesses in Guildford and the surrounding area. Across Surrey, we cover 395 places, and Guildford is one of them. You can also see our page for Crawley, about 19 miles away.

Fire rated sealant for homes and businesses in Guildford
Filling a fire-stopping gap with standard silicone or caulk doesn’t make it fire-rated. We cut out the wrong material and the gap is resealed with a product tested for that use. We work on service penetrations, door frames and plasterboard & masonry, and people most often call us about fire seals that have cracked with movement and open joints along the top of partitions.
Guildford has offices, shops, places to stay and schools as well as homes, all with washrooms, kitchens and service openings that need the right sealant. We cover both day-to-day sealant and fire-rated sealant, installed to the manufacturer’s tested details.
You are covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.
Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Do not paint over fire sealant until it has cured
- Flag any open gap you spot round a pipe or cable
- Allow for resealing whenever new services are run
Let contractors know where fire stopping has been done, and ask them to reseal anything they cut through. Later work is a common cause of damaged fire stopping.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Doing it at the time avoids leaving gaps behind.

What the job involves on each surface
Service penetrations
Pipes, cables and ducts passing through fire-resisting walls and floors each leave a gap. We seal it with a product tested for that service and gap size.
Masonry and concrete
Brick, block and concrete walls and floors are sealed with products tested in masonry. We clean out dust and debris before sealing so the sealant bonds.
What we do, step by step
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on how many gaps there are. Jobs in a place the size of Guildford range from town-centre flats to offices and family homes. Whichever it is, tell us how to get in, where to park and where the work is.
- Before starting, we go through the specification or action list with you.
- We measure every gap and note what it’s in and what passes through.
- Unsuitable material such as ordinary foam or silicone is cut out.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your records.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed

What sealant work can’t fix
New sealant cannot fix everything, and we will tell you before any work starts. Sealant won’t put right:
- Problems with the door itself rather than the gap around the frame
- Openings too large for sealant, which need batts, boards or another system
- A wall that isn’t a fire-resisting element to begin with
If in doubt, call 0345 464 0079 or email us and we will say what we think before you book.
Surfaces we seal

Yes, we work for hotels as well as homes and businesses. A room-by-room programme keeps most rooms in use while the work goes on.
Can you do fire rated sealant in Guildford?
Yes. We work across London and the South East, and Guildford is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Can I choose the sealant colour?
Yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before we start.
Where is Mr Mastic based?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
Will you assess my building’s fire safety?
No, assessment isn’t something we do. Once you have a specification or action list from your assessor or designer, we will quote for the sealant work on it.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
