Compartment walls and floors in Havant
The area within 2 miles of Havant holds a number of hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. For England, the fire stopping of penetrations is dealt with in Approved Document B. The national BS 476 classes are due to drop out of it from 2 September 2029, leaving the European BS EN 13501-2 route, subject to transitional arrangements. Either way, we install the specified product to its tested detail.
Hotels such as The Bear Hotel, 0.9 miles south of Havant, rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. Refits at places like Central Retail Park, 0.7 miles to the south of Havant, often reroute services through walls between units.

About our fire stopping in Havant
A fire-rated sealant is only one part of a tested system: the evidence covers a specific product, wall or floor type, service, gap, depth and backing. We match each opening to that detail before any sealant goes in, and we say so if it doesn’t fit. If you’re dealing with seals disturbed by maintenance and left open and improvised or mixed-product fire seals, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Havant tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Older buildings in towns like Havant have often been rewired and replumbed several times, and each change can leave unsealed holes in walls and floors. Our applicators follow the product’s published detail for that wall or floor whenever fire-rated sealant is the chosen seal.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Signs you need fire stopping in Havant
Openings in fire-resisting walls normally appear when services are added or changed. New cabling, rerouted pipework or a data route drilled through a riser leaves an opening that nobody returns to. Across several fit-outs, the openings add up.
Clients usually get in touch after noticing one or more of the following:
- Service penetrations left open after M&E works
- Fire seals cut back for extra cables and never reinstated
- Expanding foam used as fire stopping
- Fire stopping installed outside its tested range
For a building such as St Francis, new heating or data runs are the usual reason penetrations need sealing.
What your quote should include
- How they’ll work around occupants
- How joint depth will be controlled
- How the existing material will be dealt with
- Whether primer will be used where the manufacturer specifies it
Questions we are asked in Havant
Can you seal penetrations in a hotel in Havant after a refit?
Yes. We install fire-rated and intumescent sealant where it is specified. Each seal follows the tested detail, and rooms are done in turn.
Is hospital work, at somewhere like Elmleigh Hospital, something you do?
Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
What do you charge?
Every job gets its own fixed quote. For yours, ring 01277 525 020 or email us with a description of the work.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
How a job runs
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and work section by section so the rest of the building stays in use. Parking and loading for town-centre jobs in Havant are worth mentioning when you send details. On estates and business parks it’s typically simpler.
- First we confirm the product and tested details named in the specification.
- Openings are measured and grouped by detail.
- Improvised fillers and failed sealant are removed.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Preparing the site
- Let us know about inductions and permits
- Clear stock, furniture or equipment away from the joints
- Share your working hours and any access restrictions
Ask for a quote
Send us photos, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
Related advice
Surface by surface
Masonry and concrete
Core-drilled holes are neat; broken-out ones rarely are. The gap is measured at the widest point against the detail’s limits, and any that don’t are flagged.
Metal pipes
Copper and steel pipes are a common service penetration for fire-rated sealant. The tested detail sets the pipe size range, gap, depth and whether insulation can stay on and we confirm each before sealing.
What sealant work can’t fix
Honesty saves time and money. Fresh joints won’t solve:
- Deciding what a wall or floor needs, which belongs to the designer
- Signing off or certifying a building’s fire stopping
- Construction that lacks the fire resistance the seal relies on
Not sure which it is? You can phone 01277 525 020 or use the quote form and we’ll tell you honestly before you book.

What else we do in Havant
Owners, agents and contractors
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Havant can sit alongside others in a wider programme.
Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.
After the work
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- File the specified details where the next contractor can find them
- Get seals inspected before ceilings and boxing close
- Look above ceilings when tiles are lifted for other jobs
- Agree the fire-stopping specification before services go in
Never top up a fire seal with foam, ordinary silicone or filler. Repairs need the same product and detail as the original unless the designer specifies otherwise.
A simple record of seal locations and products helps. It tells the next contractor exactly what to reinstate, which saves guesswork.
