Why act early in Sleapshyde
Fire-rated sealants need more care than everyday sealant. Depth, backing and surface preparation all affect how a seal performs, and we work to the product details every time. In a small place like Sleapshyde, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
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.
Why book with us
- Any old sealant cut out fully, not covered over
- Over 20 years’ experience

Landlords, agents and businesses in Sleapshyde
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Tell us the address, the job and how access works.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to several days, depending on how many gaps there are from start to finish. Somewhere as small as Sleapshyde, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We begin by agreeing the list of gaps from your assessor’s or designer’s requirements.
- We measure every gap and note what it’s in and what passes through.
- Any non-fire-rated filler is removed and the faces cleaned.
- The specified fire-rated sealant goes in over any backing its detail requires.
- We hand over a list of locations and products for your records.
How to prepare
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit
How to get a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll take it from there.
Advice
Common problems we fix in Sleapshyde
Door frames are a common weak spot. The architrave hides the gap between frame and wall, so it’s easy to leave unsealed when doors are changed.
Any of these means the joints need attention:
- New service routes left unsealed after building work
- Ordinary sealant used where a fire-rated product was needed
- Joints picked up in a fire-stopping survey
- Unsealed gaps around fire door frames
Rented homes near Welham Green station change hands often, and any gap left by new services in shared walls should be closed with a fire-rated product.
What to look for in a quote
- How long to leave it before use
- Which colour the sealant will be
- What product goes in the joint
- Are they insured?

Workplaces and buildings in Sleapshyde
Sleapshyde is part of Hatfield, one of the post-war new towns. Like the other new towns, Hatfield was planned with its own areas for industry and business, so workplaces sit close to the homes. Each has washrooms, kitchens and fire-rated joints to keep in order. 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.
Managing a site like Colney Heath Junior Mixed Infant and Nursery School? Then fire-stopping around service openings should be restored whenever new services go in. If you look after a church, hall or community building such as Church of St Mark, service openings in its walls need the right fire-rated sealant, as in any building.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Photograph sealed gaps before they’re covered up
- Get damaged fire seals looked at promptly
- Ask which product was used before you paint
- Keep general-purpose foam and caulk away from fire-stopping gaps
Leave the sealant to cure fully before painting near it. Some fire-rated sealants can be painted and some cannot, so ask us which we used.
A gap left open in a fire-resisting wall or floor lets smoke spread in ways the building wasn’t designed for. Sealing it early is a simple step to take.
What affects the cost of fire rated sealant
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The number of rooms or windows
- Mould in or behind the old joints
- Whether the work is at height
- The old material and how stubborn it is
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please ring 0345 464 0079 or email us and we will talk you through it.
