What the job involves on each surface
Plastic pipes
In a fire, plastic pipework melts away and leaves an opening. Some intumescent sealants are tested on smaller plastic pipes, though larger ones normally call for a collar or wrap. We check the pipe material and diameter against the detail before we start.
Drylining partitions
Service holes through plasterboard are frequently oversized or ragged. If the gap exceeds the tested range, sealant alone won’t do and we will tell you what the detail says instead.
About our fire stopping in Lower Morden
Every service that crosses a compartment wall or floor leaves an opening, and that opening needs sealing to hold back fire and smoke. Our part is installing fire-rated and intumescent sealant at those openings and along linear gaps, where the specification calls for it. Each seal follows the manufacturer’s tested detail. If you’re dealing with old intumescent sealant that has split away and improvised or mixed-product fire seals, we can put it right. One point of contact handles commercial sealant work in Lower Morden from the first photos to the final walk-round, for single jobs and planned programmes alike.
Taller residential buildings in London may fall under the Building Safety Act’s higher-risk regime, where fire-stopping records get close attention. Our part is installing the specified fire-rated sealant; tell us what records you need and we’ll confirm with the quote.
Every job we finish is backed by a 12-month workmanship guarantee, in Lower Morden as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Cost factors for service penetrations
The price varies from site to site. Expect it to depend on:
- Phasing around occupants
- Removal of failed or old sealant
- The size and state of each joint
- Which sealant the job calls for
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.
Before you send an enquiry
A good diagnosis starts with the right details. Let us know:
- Whether an asbestos survey exists
- The site address and postcode
- The product your specification calls for
- When you need the work done
For a fixed quote, give us a call on 01277 525 020 or use the quote form, telling us the site location and the nature of the job. Our quote form is another easy route.
What we are called out for in Lower Morden
Some seals fail because the wrong product went in: builders’ foam or ordinary silicone used to fill a hole. The opening looks sealed but has no fire test evidence behind it and has to be removed.
Any of the following is a good reason to get the joints checked over:
- Hidden openings found during inspections
- Snag lists that include open service penetrations
- Fire sealant pulled out of the opening
- Service penetrations left open after M&E works
For a hospital such as St. Helier Hospital, 1.6 miles to the east of Lower Morden, penetration sealing is normally phased ward by ward, with infection-control rules agreed first.

Honest limits
Being straight saves everyone time. New sealant won’t cure:
- Large openings beyond what any sealant detail covers
- Gaps in walls that were never built as compartment walls
- Reviewing a building’s overall fire safety

Questions about Lower Morden
Does your area include sites such as Beverley Trading Estate, near Lower Morden?
Yes. We cover Lower Morden and the area around it, including industrial estates, business parks and retail parks such as Beverley Trading Estate. To start, just ring 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
What does the BS 476 change mean for fire-rated sealant in Lower Morden?
References to BS 476 classes are being removed from Approved Document B from 2 September 2029, after which BS EN 13501-2 classification is the route, subject to transitional arrangements. Whichever applies, we install the specified product to its tested detail; the specification is for the designer to set.
Are you insured?
Yes. We are fully insured, and the certificate can go with your quote.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How much does the work cost?
That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
Is Lower Morden in your area?
Yes. Sites across Lower Morden are covered.
Do you offer coloured sealant?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

What else we do in Lower Morden
Compartment walls and floors in Lower Morden
London’s office and residential buildings are refitted constantly, and each round of cabling or pipework can leave open penetrations. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements. In England, Approved Document B covers fire stopping of openings and penetrations. 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. We install whatever has been specified, to the product’s tested detail.

Colleges such as Merton College (to the north-east of Lower Morden) add IT and services as courses change, and each new penetration through a fire-resisting wall needs sealing with the specified product.

Our process
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We ask for the product and detail your designer has specified.
- We sort the openings by the detail each one needs.
- Old or wrong materials are cut out.
- Where the detail needs backing, it goes in at the stated depth.
- Fire-rated or intumescent sealant goes in around the services and is tooled off.
- We walk the completed areas with you and confirm the records agreed at quote stage.
Before we start on site
- Point out parking and an unloading spot
- Move anything stored against the joints
- Warn occupants and staff about the work
