No. We work neatly, protect the area around the joints and tidy up afterwards.
About our fire rated sealant in Lyford
Intumescent sealant looks much like any other sealant until it gets hot; in a fire it expands into the joint. Which product suits a gap depends on its width, the materials either side and what runs through it, so we follow the tested detail for each one. Typical jobs include new service routes left unsealed after building work and cracked or shrunken fire-rated sealant, across plasterboard & masonry, door frames and linear gaps.
In a village or hamlet like Lyford, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. Each still needs sound sealant in its washrooms and kitchens, and fire-rated joints where services pass through walls.
All our work is covered by a one-year guarantee.

What we cannot put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Sign-off of the building, which sits with building control or your assessor
- Fire risk assessments, which need a qualified assessor
- A wall that is not a fire-resisting element to begin with
Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.
Joints and surfaces we work on
- Plasterboard & masonry
- Linear gaps
- Service penetrations
- Pipe & cable gaps
- Door frames
- Flats & HMOs
Can I do it myself?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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.

Fire rated sealant in Lyford: local notes
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, 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.
In and around Lyford, as anywhere, good fire rated sealant starts with a clean, dry, properly prepared joint.

What affects the quote in Lyford
Your quote is based on your job. We take into account:
- Any mould that needs treating
- The number and length of the joints
- Working hours on commercial sites
- Access and height
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
What to tell us for a quote
When you contact us, it’s useful to know:
- The rough size of the job
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
- If someone has resealed it before
For a quick quote, get us on the phone, or email us if that is easier. Tell us about the joints that need doing and we will explain what’s involved.
How the visit works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a few hours for a handful of gaps, and longer for a whole building. Somewhere like Lyford needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the gaps on your list or survey and check each one’s size and substrate.
- Anything that is not fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Finally, we list where we worked and what we used, for your records.
Getting ready for the visit
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- Tell us about any previous sealing or DIY attempts

What else we do in Lyford
When to call us in Lyford
Lots of unsealed gaps appear long after the building was completed. New cables, pipes and data runs go through walls and ceilings and the hole round the new service isn’t always sealed again.
Keep an eye out for these signs:
- Gaps flagged on a fire risk assessment
- Gaps left after a refit or conversion
- Gaps around pipes and cables through fire-resisting walls
- Linear gaps at the head of walls
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.
What to look for in a quote
- Whether VAT is included
- How the colour is chosen
- What happens if the job turns out different
- Are they insured?
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Do not paint over fire sealant until it has cured
- Photograph sealed gaps before they’re covered up
- Keep general-purpose foam and caulk away from fire-stopping gaps
- Check risers, ceiling voids and cupboards during building checks
Follow the cure time we give you before decorating over the sealant. Some fire-rated sealants can be painted and some can’t, so ask us which we used.
It’s easiest to seal gaps while they’re few and easy to reach. Leave them and each new job adds another hole and the list grows.
