FAQs: Liss
Do you seal service penetrations in hotels around Liss?
Yes, to the specification and the product’s tested detail. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
Is Ham Barn Business Park, near Liss, within your area?
Yes. Estates, retail parks and business parks around Liss, Ham Barn Business Park among them, are all within reach. To start, just call 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Can the sealant be colour-matched?
It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Send details for a fixed quote.
Can weather delay the job?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Can you send site paperwork?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.
How much does the work cost?
Every job gets its own fixed quote. For yours, ring 01277 525 020 or send photos by email with a description of the work.
Fire stopping in Liss, done properly
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’ll confirm with the quote. We work on small duct penetrations where the tested detail allows, pipe penetrations and joints between fire-resisting walls and floors, and the failures we are asked to look at most are snag lists that include open service penetrations and fire seals cut back for extra cables and never reinstated. Whoever orders the work in Liss, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Buildings in a smaller place such as Liss that need fire-rated sealing are typically schools, care homes, surgeries, small offices and flats over shops. Around those penetrations, fire-rated sealant is installed if specified, with depth, backing and gap all as tested.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When something else is needed
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Fire doors, dampers or other fire safety equipment
- Designing or specifying fire stopping, which sits with the designer or fire engineer
- Walls or floors that aren’t fire-resisting to begin with
If in doubt, call 01277 525 020 or email a schedule or drawings and we will say what we think.
Joints and surfaces we work on
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Cable penetrations
- Pipe penetrations
- Service gaps in risers
- Small duct penetrations where the tested detail allows
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Commercial clients in Liss
We work for building owners and managing agents on everything from one building to a spread of sites. Several sites can go on one quote, which keeps the paperwork simple.
As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.
What sets the cost
There’s no standard rate for sealant work, because every site is different. What we take into account:
- The size and state of each joint
- Site requirements such as inductions and permits
- Whether old sealant has to be cut out first
- Which sealant the job calls for
A quote for service penetrations depends on quantities, condition and access, plus any specification you are working to. Call for a quote.
What to include in your enquiry
We can often quote from photos and a few details. Please tell us:
- Photos of the joints, close up and from further back
- The site address and postcode
- Approximate linear metres or a joint schedule
- What the building is and how it’s used
Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, call 01277 525 020 or send details through our quote form.
Diagnose, treat, sign off
Tell us your site hours and access windows and we’ll plan around them. While we are working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. For a job in Liss, the main thing is a clear picture of the work, so send photos of each area. You’ll then get a fixed price for the work.
- First we go through the drawings, schedule or specification for the seals and raise any questions before we price.
- On site, each opening is checked against the tested detail it is meant to follow.
- Unsuitable fillers and loose debris are taken out of each opening.
- Mineral wool or other backing goes in wherever the detail asks.
- Fire-rated or intumescent sealant is gunned in to the specified depth, then tooled.
- Openings that need a collar, wrap, batt or other product are flagged to you rather than filled with sealant.
Preparing the site
- Point out parking and an unloading spot
- Tell staff and tenants when we’ll be in
- Let us know about inductions and permits

Keeping the joints sound
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. Our advice:
- Brief every trade that openings they make must be sealed
- Arrange inspection before areas are covered up
- Record which product was used where
- Leave fire sealant to cure fully before covering it
Add risers, plant rooms and ceiling voids to routine fire-stopping checks. Watch for cracked sealant, new services with no seal and openings that have grown, 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.
Service penetrations in Liss buildings
Fire stopping of openings and penetrations in England falls under Approved Document B. References to the older BS 476 classes are being removed from it from 2 September 2029, after which the European classification, BS EN 13501-2, is the route, subject to transitional arrangements. Either way, we install the specified product to its tested detail. Central London is about 47 miles from Liss. Office refits around the commuter belt bring new cabling through fire-resisting walls; the gaps need the specified seal.
Offices at parks like Ham Barn Business Park, 1.3 miles to the north-west of Liss, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail. On a hospital site such as Petersfield Community Hospital, 3.6 miles south-west of Liss, fire-rated sealant goes in where the specification calls for it, with the work planned around the estates team’s permits. Schools such as Liss Infant School often have new data and services installed during holidays, and penetrations through fire-resisting walls should be checked afterwards.
