How fire rated sealant works in Portsmouth
Later work by other trades often breaks through fire stopping, especially in flats, HMOs, offices and schools. A new cable run or a replaced pipe can leave an open hole behind. Those are the gaps we close, using a tested fire-rated product. We work on pipe & cable gaps, flats & HMOs and door frames, and people most often call us about fire seals that have cracked with movement and unsealed gaps around fire door frames.
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. It usually takes a few hours for a handful of gaps, and longer for a whole building.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Old or unsuitable sealant is cut out and the gap cleaned.
- We put in whatever backing or fill the product detail specifies.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- We record the locations and products used for your records.
What you will pay
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
What you get with us
- Neat joints and a tidy finish
- Experience in homes, commercial sites and hotels
- A 12-month guarantee on all work
- Sanitary silicone with an anti-fungal additive in wet areas

What’s near Portsmouth
We work in homes and buildings around Manor Infant School, Alexandra Park and St Wilfrid and the streets around them. You’ll also find The Druids Arms (less than half a mile north-east), The Portsmouth Academy (under half a mile south-east) and St Edmund's Catholic School (0.7 miles south-west). The nearest railway station is Fratton station, roughly 0.9 miles south of the centre. A little further out are Royal Portsmouth Hospital (0.7 miles south-west) and Charles Dickens Birthplace Museum (under half a mile west). The countryside around Portsmouth includes Milton Locks and Portsdown Hill.
Commercial buildings across Portsmouth
Hotels, landlords, schools and businesses across Portsmouth all have sealant to keep in order. Fire-rated sealant is installed to the manufacturer’s tested details, and washroom sealant is chosen for heavy use.
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings. For any job in Portsmouth, joints are cleaned back properly before anything new goes in. Along the coast in Portsmouth, holiday lets and guest houses can have bathrooms in near-constant use, which is hard on sealant and grout, and the weather is hard on the outside too.
Portsmouth: Letting a property close to Fratton station? Then any gap left by new services in shared walls should be closed with a fire-rated product. Community buildings like St Wilfrid are part of the picture too: service openings in its walls need the right fire-rated sealant, as in any building.
What we are called out for in Portsmouth
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
Look out for any of the following:
- Gaps around pipes and cables through fire-resisting walls
- Unsealed gaps around fire door frames
- Fire seals that have cracked with movement
- Fire stopping disturbed by later work
Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
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.
How we quote for fire rated sealant
We do not publish a price list, because jobs vary so much. The quote depends on:
- How much old sealant there is and how hard it is to remove
- Whether the work is at height
- The type of sealant required
- The size of the job
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll explain what it covers.
What to tell us for a quote
Photos by email are helpful but not essential. Try to tell us:
- Photos by email, if that is easy
- Whether it’s a home or a business
- The rough size of the job
- What the problem is, such as mould, gaps, leaks or cracking
To get a quote, phone 0345 464 0079 or email us with the location and a short description of the problem. We’ll give you a clear quote before any work starts.
Landlords, agents and businesses in Portsmouth
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
We also work for property managers and facilities teams across Portsmouth. We can quote a run of properties together, and we’re fully insured.
Different surfaces, different methods
Door frames
A door can only do its job if the gap behind its frame is sealed too. We fill it with a fire-rated product suited to the materials either side.
Masonry and concrete
Holes through concrete and block are rarely neat. We measure the gap at its widest point against the product’s tested range.
Portsmouth: your questions answered
Is it messy?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Are you ARBOMaster approved?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
What information do you need?
A short description and the location, with pictures by email if possible. If we need more, we’ll ask.
Can I add another job to the visit?
Yes. More than one area can be quoted together.
Is the work guaranteed?
Yes: twelve months. If anything is not right with the work within the year, let us know and we’ll sort it.
Can I do it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
