Frieth questions
Do you cover Frieth for fire rated sealant?
Yes. Our work covers London and the South East, and Frieth is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear quote.
Do you cover smaller places like Frieth?
Yes. Frieth is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What should I tell you?
The location, the problem and the rough size of the job. Photos by email help too.
What does intumescent mean?
An intumescent sealant expands when it gets hot, helping close the gap. It’s one type of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you work in occupied buildings?
Yes. We regularly work in flats, HMOs, schools and offices while they’re in use and we plan access around the people using them. Early starts or out-of-hours work can be arranged where it’s needed.
Fire rated sealant in Frieth
A gap around a door frame, a linear joint at the head of a wall and a hole round a pipe are each sealed differently. Measuring the gap and checking what it’s made of comes first, then the sealant goes in to the depth the product’s details set. If you’re dealing with linear gaps at the head of walls and fire seals that have cracked with movement, we can help.
In a village or hamlet like Frieth, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
Big or small, it’s backed by our 12-month guarantee.

How it works
Before we leave, we go over the finished joints with you. The work normally takes from a few hours to a few days, depending on the number of gaps and the access, depending on the size of the job. Somewhere as small as Frieth, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- The specified fire-rated sealant goes in over any backing its detail requires.
- Every location is recorded with the product used for your files.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we are working on
- On commercial sites, let us know about site rules

What affects the quote in Frieth
For a quick quote, just ask. What matters most is:
- How much old sealant there is and how hard it is to remove
- When we can work, for business premises
- How easy the joints are to reach
- Which sealant suits the joint
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we’ll explain what it covers.
What to tell us for a quote
When you call or email, these details help:
- How many joints, rooms or windows are involved
- Pictures of the joints, sent by email
- The problem you’ve noticed
- Whether it’s a home or a business
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
What happens if it’s left?
Sealant is not the fix for every opening. Large holes, cable bundles and plastic pipes can call for batts, collars or wraps. If a gap isn’t suitable for sealant, we will tell you. Around Frieth, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Honest limits
New sealant can’t fix everything, and we’ll tell you before we start. Sealant won’t put right:
- A wall that is not a fire-resisting element to begin with
- Big openings where sealant alone isn’t the tested solution
- Fire risk assessments, which need a qualified assessor
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.

Surface by surface
Door frames
Behind most architraves is a gap between frame and wall. Where it’s open, we seal it to the product’s details for that gap size so the architrave can be refitted.
Masonry and concrete
Preparation counts on brick, block and concrete. The gap is cleaned and backed where required before the sealant goes in.

Fire rated sealant around Frieth
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.
If you look after a church, hall or community building such as Church of St John the Evangelist, gaps around pipes and cables are worth checking after any building work there. Schools such as Frieth Church of England Combined School are buildings too, and service openings in fire-resisting walls need checking after any refurbishment. If you let a flat or house near Marlow station, fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through.
