Can you work at a site such as Murrell Green Business Park, by Greywell?

Do you work on fire-rated sealing in hotels in Greywell?
Yes, where the specification calls for fire-rated sealant. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Do you need to see the site first?
Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit before quoting.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you have public liability insurance?
Yes. We are fully insured, including public liability cover.
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member.
About our fire stopping in Greywell
On a fit-out or refurbishment, we follow the services contractors floor by floor. We work from your penetration schedule or marked-up drawings alongside the manufacturer’s details. Tell us what records you need and we will confirm with the quote. Site teams most often ask us about snag lists that include open service penetrations and fire seals cut back for extra cables and never reinstated, across service gaps in risers, linear gaps at wall heads and small duct penetrations where the tested detail allows. A single leaking joint is often how a building in Greywell first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
A job near Greywell is typically planned around one visit, so send the specification and photos first. We install to the specification and the manufacturer’s guidance, leaving design and sign-off with the designer and building control.
Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Aftercare for building managers
A few simple habits keep the new joints working:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Keep general-purpose fillers away from compartment walls
- Look above ceilings when tiles are lifted for other jobs
- Agree the fire-stopping specification before services go in
During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged, and report them promptly.
The simplest way to keep compartment walls intact is to plan fire stopping into every job that crosses them. Then the seal goes in while the area is open instead of being left for someone else.

Why deal with it now?
An improvised seal can look finished while offering no tested performance. Correcting it means cutting it out and starting again with the specified product. One visit to deal with every failing joint makes more sense than several trips to a place like Greywell, rather than one at a time. Send photos of each area and we’ll quote for the lot.
No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Compartment walls and floors in Greywell
A number of hotels sit less than 2 miles from Greywell. In hotels, bedroom and corridor walls are normally fire-resisting, so services added in a refit need sealing with the specified product. 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. Our part stays the same: the specified product, installed to its tested detail.
Tenant changes at parks like Murrell Green Business Park, 2.6 miles north-east of Greywell, bring new data and services, and openings through fire-resisting walls need the specified seal. In a hotel such as Basingstoke Country Hotel, 1.2 miles north-west of Greywell, new pipework or cabling through bedroom and corridor walls needs sealing with the specified product.
Greywell is about 6 miles east of Basingstoke, in Hampshire. Anywhere in RG29, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 723 places in Hampshire. Reading is covered too, around 13 miles from Greywell.

When something else is needed
We check first that sealant really is the fix. It won’t put right:
- Issuing fire ratings or certificates for seals
- Deciding what a wall or floor needs, which belongs to the designer
- Gaps in walls that were never built as compartment walls
If you’re not sure, just call 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Our process
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Rural sites near Greywell may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.
- The specification and schedule come first, so we know which details apply.
- Access, permits and the order of areas are agreed with the site team.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned first.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
What we need from you
- Share the asbestos register for older buildings
- Clear stock, furniture or equipment away from the joints
- Tell us which areas need to stay in use

When to call us in Greywell
A common fault is a product that was never fire-rated in the first place: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it, so it has to come out.
Typical triggers for a call:
- Builders’ foam or ordinary silicone in compartment walls
- Hidden openings found during inspections
- Improvised or mixed-product fire seals
- Head-of-wall gaps with no fire seal
Older community buildings such as Church of St Mary the Virgin that have been rewired or given new heating can have service gaps through walls worth checking against the specification.

Should maintenance staff do it?
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
