Questions from Mount Pleasant
Do you work for landlords with property near Stansted Mountfitchet station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Will you come out to Mount Pleasant?
Yes. Mount Pleasant is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Can you seal over the old sealant?
No. The old sealant always comes out first, so the new joint bonds to clean surfaces.
Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
How long does fire rated sealant take?
It depends on the size of the job, but most jobs take a few hours for a handful of gaps, and longer for a whole building. We will tell you when we quote.
Do you offer different sealant colours?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Is there any odour?
There can be a smell while the sealant cures. Ventilation helps.
Fire rated sealant in Mount Pleasant
Fire stopping only performs as intended if it’s done to the detail: correct depth, correct backing and a product suited to the surfaces. That is the part we focus on. If you’re dealing with open gaps behind door architraves and open holes round services passing through fire walls, we can help, whatever the surface.
For a small place like Mount Pleasant, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.
All of our work is guaranteed for twelve months.

When it isn’t the sealant
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Fire risk assessments, which need a qualified assessor
- Problems with the door itself rather than the gap around the frame
- Walls or floors that weren’t built to resist fire
If you are not sure, just ring 0345 464 0079 or send us an email and we’ll give you a straight answer.
What we seal
- Plasterboard & masonry
- Door frames
- Linear gaps
- Pipe & cable gaps
- Flats & HMOs
- Service penetrations
How to look after the new joints
After the cure time, these simple habits help:
- Check risers, ceiling voids and cupboards during building checks
- Photograph sealed gaps before they’re covered up
- Do not fill fire-stopping gaps with ordinary foam or silicone
- Make resealing part of every contractor’s brief
Include fire stopping in your regular building checks. Look for cracks, gaps or sealant that has been cut or pulled out and have them put right.
When you plan work that goes through walls or ceilings, plan the fire stopping too. Catching it then saves a separate visit later.
What affects the cost of fire rated sealant
Some jobs are bigger than they look, and some smaller. The main factors:
- The old material and how stubborn it is
- Whether there’s mould to deal with
- Which sealant suits the joint
- The size of the job
Rather than a set price list, 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.
What to tell us for a quote
When you call or email, it’s useful to know:
- Roughly how big the job is
- A few photos by email, if you can
- Any access issues, like height or stairs
- Where the job is, and your postcode
For fire rated sealant in Mount Pleasant, phone 0345 464 0079 or send us an email. A short description of the job and where it is helps us quote, and you’ll get a clear quote before we start.
What happens if it’s left?
An open gap in a fire-resisting wall is a route for smoke and fire. A proper seal lets the wall do its job again, and the sealing itself is often a contained piece of work. Around Mount Pleasant, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. Most jobs take from a few hours to a few days, depending on the number of gaps and the access. Somewhere like Mount Pleasant needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We start with the survey or action list, checking the size and surfaces of every gap.
- We remove any old or unsuitable filler and clean the gap.
- Where the tested detail needs backing or fill, we fit it.
- We apply the fire-rated or intumescent sealant to the specified depth and tool it.
- We record the locations and products used for your records.
Before we arrive
- Clear the area around the work
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints
