Common problems we fix in Lee
When a seal departs from its tested detail, the evidence no longer covers it. Gaps beyond the tested size, shallow sealant, no backing where it was needed, or products from different systems mixed together are what we find most often.
Any of the following is a good reason to get the joints checked over:
- Snag lists that include open service penetrations
- Fire-rated sealant that has cracked or shrunk back
- Hidden openings found during inspections
- Fire seals cut back for extra cables and never reinstated
Residences at universities like University of Southampton (to the south-east of Lee) have compartment walls that must be resealed whenever services change.

About our fire stopping in Lee
Fire-rated sealant suits many small service penetrations: copper and steel pipes, cables and some small ducts where the tested detail allows. Larger openings and some plastic pipes call for collars, wraps, batts or boards instead. We use sealant where it is the specified product, and we tell you when a detail calls for something else. We work on small duct penetrations where the tested detail allows, service gaps in risers and cable penetrations, and the usual reasons a site gets in touch are fire sealant pulled out of the opening and improvised or mixed-product fire seals. For commercial sealant work in Lee, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Around smaller places like Lee, penetration seals come up in schools, halls, pubs with rooms, care homes and farm buildings used as offices. Any service penetration through those walls should be closed with the specified product, set out as its test evidence shows.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

From enquiry to sign-off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. Jobs in and around smaller places like Lee are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We start with your penetration schedule, drawings or specification.
- 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.
Getting the site ready
- Share the asbestos register for older buildings
- Tell us your opening times and when work is allowed
- Explain the parking and delivery arrangements

Looking after the joints
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Put resealing into every M&E and fit-out package
- Check with the data sheet before painting over fire sealant
- Keep product data and details in the fire safety file
- Include service cupboards in routine inspections
During planned inspections, look at seals in risers, cupboards and voids. Look for cracks, unsealed new cables and gaps that have been enlarged.
Looking at service areas on a regular cycle pays off. Catching a damaged seal early keeps the fix small compared with dozens found at once.
Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.
Why it’s worth doing now in Lee
An open or wrongly sealed service penetration lets fire and smoke reach the next compartment much sooner than the building was designed for. Putting it right is usually a modest job when the openings are accessible. Wait until ceilings close or areas are occupied and the same work becomes harder to reach. For buildings around smaller places like Lee, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Why us?
- One contact handling all your sites
- Products installed to the manufacturer’s instructions

Lee: questions and answers
What does the BS 476 change mean for fire-rated sealant in Lee?
Approved Document B loses its BS 476 references from 2 September 2029, and BS EN 13501-2 becomes the route, subject to transitional arrangements. Our part doesn’t change: the specified product, to its tested detail.
Is Lee too small for you to travel to?
No. Places such as Lee are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.
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 if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
What hours do you work?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Fire stopping around Lee: what changes locally
A 2-mile radius around Lee takes in a number of hotels. In hotels, bedroom and corridor walls are usually fire-resisting, so services added in a refit need sealing with the specified product. Approved Document B is the English guidance that covers fire stopping around 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. What we install is set by the specification, and it goes in to the tested detail.
For a unit at a site such as Crescent Industrial Estate, 1 mile south of Lee, new power or data runs between office and warehouse can breach a compartment wall. At a college such as Totton College, 2.7 miles south of Lee, checking penetration seals after summer M&E works is good practice.
