Fire rated sealant in Lagness, done properly
Door frame gaps, linear joints and holes around services all have their own details. We check the size and the substrate before choosing the product, then apply it to the depth its tested detail calls for. If you have unsealed gaps where pipes and cables go through a wall and holes left by a change of layout, we can put it right, whatever the surface.
For a small place like Lagness, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
You’re covered for a year from the day we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

Leave it or put it right?
An unsealed gap lets smoke and fire get round a wall that was built to hold them back. Sealing it properly restores what the wall was there to do, and the sealing itself is often a contained piece of work. In a small place like Lagness, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What we do, step by step
The work is kept neat and contained to the area we are working on. The job generally takes from a few hours to a few days, depending on the number of gaps and the access.

Advice
What we’re called out for in Lagness
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.
Look out for any of the following:
- Fire stopping disturbed by later work
- Open holes round services passing through fire walls
- Gaps left after a refit or conversion
- Cracked or shrunken fire-rated sealant
Managing a site like Rose Green Junior School? Then gaps opened by contractors for new cabling are a common finding in schools and offices.
Questions to ask before you book
- Whether all the old sealant comes out first
- Is VAT in the price?
- How the colour is chosen
- What guarantee comes with the work
Fire rated sealant around Lagness
If you run a hotel, guest house or holiday let in a coastal place like Lagness, heavy use in the busy months is hard on washroom and kitchen sealant, and any building work there should leave fire-rated joints made good. Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, 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 Bognor Regis station change hands often, and fire-rated sealant around pipes and cables through walls and floors needs making good whenever new services go through. For buildings such as Church of St Giles, gaps around pipes and cables are worth checking after any building work there.

Lagness questions
Is Lagness within the area you cover?
Yes, Lagness is covered. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you cover Lagness for fire rated sealant?
Yes. We work across London and the South East, and Lagness is part of that. Just ring 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
How long will you be here?
Most jobs take a few hours for a handful of gaps, and longer for a whole building, including preparation and clearing up. Your quote will say how long we expect yours to take.
Which products do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Where is Mr Mastic based?
We work from Crawley. We cover Lagness and the rest of West Sussex.
Will we have a record of what was sealed?
Yes. Locations and products are written up when we finish. Tell us if your assessor needs it in a particular format.
How the job changes by surface
Plasterboard walls
Holes in plasterboard are often cut roughly for services. Gaps that are too big for sealant alone need a different detail.
Flats and HMOs
Converted houses often have gaps around old and new services. The gaps on your list are sealed with a fire-rated product and the locations noted.
