Where services cross fire walls in Roundshaw
Roundshaw has plenty of hotels close by, all within 2 miles. In hotels, bedroom and corridor walls are typically fire-resisting, so services added in a refit need sealing with the specified product. In England, Approved Document B covers fire stopping of openings and penetrations. 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. Either way, we install the specified product to its tested detail.
Hotels such as London Croydon Aerodrome Hotel (to the east of Roundshaw) rely on fire-resisting walls between bedrooms and corridors, and refits that add services leave penetrations to seal where fire-rated sealant is specified. Tenant changes at centres like Whitgift Centre, 2 miles north-east of Roundshaw, often mean new services through walls between units. For a site team at a college like Purley Language College, which lies south-east of Roundshaw, fire-rated sealing is best scheduled after the summer works.
Roundshaw is about 2 miles south-west of Croydon, in Greater London. Anywhere in SM6, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Our Greater London coverage takes in 764 places, large and small. For work in that direction, see our London page, about 10 miles away.
If you need fire stopping in SM6, CR8 and CR0, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. If your site is on Link Lane, Milton Road and Redwing Road or close by, send details and we will quote for service penetrations. Sites close to Roundshaw are covered too, including Russell Hill (1 mile east), Bandonhill (1 mile north), Peaks Hill (1 mile south), Waddon (1 mile north-east) and Wallington (1 mile north-west). Bigger towns within reach include London (10 miles north), City of Westminster (11 miles north), Marylebone (11 miles north), Kensington (11 miles north), St Pancras (12 miles north) and Shoreditch (12 miles north).
Local landmarks in Roundshaw

For rail, the closest station is Wallington station, roughly 0.9 miles north-west of the centre.

Fire stopping in Roundshaw
Opened ceilings and riser doors often reveal service openings nobody sealed. Where the walls and floors already have a fire-stopping specification, we can work to it using the product and detail it sets out. With no specification in place, the first step sits with your designer or fire engineer, not with us. We work on cable penetrations, small duct penetrations where the tested detail allows and linear gaps at wall heads, and the usual reasons a site gets in touch are openings left by services added after handover and unsealed penetrations discovered above suspended ceilings. One point of contact handles commercial sealant work in Roundshaw from the first photographs to the final walk-round, whether it’s one building or several.
In London, higher-risk residential buildings under the Building Safety Act bring extra scrutiny of fire-stopping records. 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, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Plastic pipes whose detail calls for a collar or wrap
- Construction that lacks the fire resistance the seal relies on
- Writing the fire-stopping specification
If in doubt, call 01277 525 020 or send details through our quote form and we’ll say what we think.
Surfaces we seal
- Pipe penetrations
- Cable penetrations
- Linear gaps at wall heads
- Joints between fire-resisting walls and floors
- Small duct penetrations where the tested detail allows
- Service gaps in risers
What sets the cost
What shapes the price:
- Phasing around occupants
- Which sealant the job calls for
- Quantities, in metres or numbers
- Removal of failed or old sealant
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.
What to include in your enquiry
Good information means a firmer quote. When you get in touch, include:
- Photos of the joints, close up and from further back
- Asbestos survey details if the building is older
- Whether the building will be occupied during the work
- The postcode of the building
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or email the details over.

Site staff or a sealant specialist?
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.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Keep general-purpose fillers away from compartment walls
- Leave fire sealant to cure fully before covering it
- Settle who seals which penetrations at the start of a project
- File the specified details where the next contractor can find them
Once the seals are in, tell other trades they exist and must not be disturbed. Any seal cut back for a new service needs reinstating to its tested detail.
Specify fire stopping early on refits, not as an afterthought. Details can then be picked to suit the actual pipes, cables and ducts.
Common questions from Roundshaw clients
Do you take on jobs in Roundshaw where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly.
Can you seal around new services in a hotel near Roundshaw?
Yes, to the specification and the product’s tested detail. Work is done room by room so the hotel keeps trading; design and sign-off stay with the designer and building control.
Do you take on small jobs?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Is the work guaranteed?
Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
Can staff carry on working while you’re here?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Our process
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. All of Greater London is in the ULEZ, and kerbside space in Roundshaw can be scarce. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- 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.
- Foam, ordinary sealant and debris come out.
- Backing and fire-rated sealant are installed to the detail and tooled.
- We tell you about openings that need a different product.
Preparing the site
- Send asbestos survey details if the building is pre-2000
- Tell us your opening times and when work is allowed
- Arrange parking or a loading space
