How we handle fire rated sealant in Andover
In flats, HMOs, offices and schools, fire stopping is often disturbed by later work. One new cable or pipe can leave a gap that nobody goes back to seal. Those are the gaps we close, using a tested fire-rated product. Typical jobs include open gaps behind door architraves and gaps flagged on a fire risk assessment, across linear gaps, service penetrations and pipe & cable gaps.
Washrooms in busy buildings wear their sealant out faster than a bathroom at home, while fire-rated sealant has to be made good whenever new pipes or cables go through. For a building in Andover, we plan timings around how it’s used.
All our work is covered by our 12-month guarantee, wherever you are in Hampshire.

How it works
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes from a few hours to a few days, depending on the number of gaps and the access. Parking in a town like Andover is normally straightforward, but tell us if there’s a driveway or any restrictions, and mention if the work is upstairs, in a flat or high on the outside.
- We start with the survey or action list, checking the size and surfaces of every gap.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Where the tested detail needs backing or fill, we fit it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
How to prepare
- For indoor joints, keep the area dry beforehand if you can
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work

Fire rated sealant around Andover
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 apply fire-rated sealant to the assessor’s or designer’s specification and the product’s tested details. Andover has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed.
Community buildings like Church of St Mary are part of the picture too: gaps around pipes and cables are worth checking after any building work there. For landlords with property near Andover station, any gap left by new services in shared walls should be closed with a fire-rated product.

A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
What we can’t put right
A few problems are outside what sealant work can do:
- Walls or floors that weren’t built to resist fire
- Sign-off of the building, which sits with building control or your assessor
- Problems with the door itself rather than the gap around the frame
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Allow for resealing whenever new services are run
- Check whether a sealant can be painted before decorating over it
- Check risers, ceiling voids and cupboards during building checks
- Keep the record of products and locations with your fire safety documents
Keep the record we give you with the building’s fire safety documents. It helps whoever checks the building next.
It’s easiest to seal gaps while they’re few and easy to reach. Over time, more work adds more holes and the job gets bigger.
Signs you need fire rated sealant in Andover
Buildings are refitted and reconfigured over the years. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
The problems people generally mention when they call include:
- Gaps where walls meet ceilings or slabs
- Damaged fire sealant left by other trades
- Door frames with gaps between frame and wall
- New service routes left unsealed after building work
Managing a site like St John the Baptist Catholic Primary School? Then fire-stopping around service openings should be restored whenever new services go in.

FAQs for Andover
Do you cover Andover for fire rated sealant?
Yes, Andover is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or drop us an email with a few details of the job.
Do you take on hotel work around Andover?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Andover, along with the rest of our area.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we’ll explain our choice.
What fire rating will the seal have?
That is not something we state or certify. Your specification sets the requirement, and we apply a product tested for it, recording the locations and products.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
How do I get a quote for fire rated sealant in Andover?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before any work starts.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Landlords are often happy for the work to be arranged.
Should I try it myself first?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

Why deal with it now?
Items left open on a fire risk assessment tend to come back at the next review. Getting them done and written up means you can show the action was taken. Draughts from a gap round a frame, damp under a sill or water behind a bath panel all start small, and they’re far easier to fix early.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.
