Fire stopping for commercial buildings in Loyter's Green
We are commercial sealant applicators, CHAS accredited and a Constructionline member, with CSCS-carded applicators on site. We don’t hold a third-party fire-stopping installer certificate, and we won’t pretend otherwise. What we offer is careful installation of the specified sealant to its tested detail, with a 12-month guarantee on our workmanship. The enquiries we see most involve builders’ foam or ordinary silicone in compartment walls and service penetrations left open after M&E works, on pipe penetrations, cable penetrations and linear gaps at wall heads. For commercial sealant work in Loyter's Green, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
For a smaller site near Loyter's Green, we plan to do all the penetrations in one go, so send the specification and photographs first. Design and sign-off belong to the designer or building control; we install what’s specified.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Doing it in-house
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Loyter's Green: questions and answers
Is Loyter's Green off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Does your area include sites such as Hastingwood Business Centre, near Loyter's Green?
Yes. We cover Loyter's Green and the area around it, including industrial estates, business parks and retail parks such as Hastingwood Business Centre. Photos and a short description are enough for a first look.
What if there’s asbestos in the old mastic?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
What will the job cost?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.
Does the weather affect the work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.
Can you seal any opening with fire-rated sealant?
No. It depends on the tested detail for that wall or floor and service. Large openings, many plastic pipes and some ducts need collars, wraps, batts or boards, and we flag those rather than improvise.
How a job runs
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes longer where risers, ceiling voids or occupied floors have to be worked through in sequence, and our waste is bagged and taken away as we go. For work around Loyter's Green, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- We compare every service penetration with its tested detail before sealing.
- Unsuitable material is removed and the opening cleaned so the seal starts clean.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Make sure the joints can be reached
- Arrange parking or a loading space
- Share the asbestos register for older buildings

What affects the price in Loyter's Green
Your fixed quote is built from the real scope. It allows for:
- Distance, for remote addresses
- Site requirements such as inductions and permits
- Specialist products, such as fire-rated or hygienic sealants
- Joint width, depth and condition
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote once you have the details.
What to include in your enquiry
Diagnosis starts before we arrive. Let us know:
- Rough lengths or quantities, or drawings if you have them
- When you need the work done
- Any specification or named product
- Whether the building will be occupied during the work
Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
When to call us in Loyter's Green
Linear gaps fail where a fire-resisting wall meets a slab, soffit or another wall. Deflection and building movement can open these gaps, and the wrong product can split as a result. The tested detail for a linear joint states the width and movement it covers.
What tends to prompt an enquiry:
- Unsealed penetrations discovered above suspended ceilings
- Builders’ foam or ordinary silicone in compartment walls
- Old intumescent sealant that has split away
- Unsealed joints where partitions meet the slab
For a building at a site such as Hastingwood Business Centre, which lies south-west of Loyter's Green, a check of penetration seals after each fit-out is good practice.
Comparing quotes
- Whether old or failed sealant will be cut out, not overlaid
- Whether primer will be used where the manufacturer specifies it
- How joint depth will be controlled
- What site paperwork they can supply
Why act early in Loyter's Green
Open service penetrations matter on ordinary days, not just in a fire: they also carry noise, draughts and smells between rooms. The specified fire seal closes the gap for all of these and the building feels the difference. Halls, stores and units around places like Loyter's Green may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.
The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we’ll explain how it’s made up.
What you get with us
- A Constructionline member, so easy to vet
- One number for every site we cover
- Over 20 years of commercial sealing
- Failed material removed, not covered up

When something else is needed
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Approving the work on behalf of building control
- Large openings beyond what any sealant detail covers
- Designing or specifying fire stopping, which sits with the designer or fire engineer
If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.
What we seal
- Service gaps in risers
- Linear gaps at wall heads
- Cable penetrations
- Pipe penetrations
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
