Fire-rated sealant in Upper Swanmore, Hampshire
Intumescent and fire-rated sealant around gaps, frames and service penetrations for homes and businesses in Upper Swanmore and across Hampshire. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Cracked or shrunken fire-rated sealant
- Damaged fire sealant left by other trades
- Unsealed gaps where pipes and cables go through a wall
Common problems we fix in Upper Swanmore
Gaps also open up as buildings move: cracked or debonded sealant leaves an open route through the wall. Damage from cleaning, knocks and maintenance adds to it.
Keep an eye out for these signs:
- Fire stopping disturbed by later work
- Open gaps behind door architraves
- Joints picked up in a fire-stopping survey
- Standard silicone or caulk in a fire-stopping gap
If you look after a church, hall or community building such as Church of St Barnabas, older buildings that have had new heating or wiring often have service gaps worth checking.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Why deal with it now?
Paying for fire stopping that has to be redone is a false economy. Work that doesn’t follow the tested detail may have to come out again once someone inspects it. Where a wall is exposed, as many are in small places like Upper Swanmore, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
We don’t show prices on the website, because each job is priced on what it involves. For a quick quote, please ring 0345 464 0079 or drop us an email and we’ll talk you through it.

Different surfaces, different methods
Linear gaps
Head-of-wall gaps are often hidden above suspended ceilings. We work along the whole run so there are no open sections left.
Service penetrations
Different services need different details: metal pipes, cables and plastic pipes are not treated the same. We follow the manufacturer’s tested detail for each.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Tell us the address, the job and how access works.
If you manage several properties in or around Upper Swanmore, several properties can go on one quote. Send us the addresses and the work at each.
Fire rated sealant around Upper Swanmore
Workplaces and the common parts of blocks of flats in England need a fire risk assessment under the Regulatory Reform (Fire Safety) Order 2005, which is often where open fire-stopping gaps are first noticed. We work to the specification you’re given, installing the product to its tested details.
For landlords with property near Botley station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant. For site and facilities teams at buildings such as Swanmore Church of England Aided Primary School, fire-stopping around service openings should be restored whenever new services go in.
