Common problems we fix in Woodside
Most open service penetrations are left by later work. New cabling, rerouted pipework or a data route drilled through a riser can leave the hole behind. Over a few years of fit-outs, a wall can collect a lot of these.
Most enquiries start with one or more of the following:
- Non-fire-rated filler around services
- Unsealed joints where partitions meet the slab
- Seals that don’t match their tested detail
- Hidden openings found during inspections
Offices at parks like Chaffinch Business Park, 1 mile north-east of Woodside, are re-cabled with each new tenant, and compartment walls need sealing afterwards to the tested detail.

How we handle fire stopping in Woodside
Facilities managers in Woodside often find open service penetrations when ceilings come down for other work. If a specification already covers those walls and floors, we can reseal to it, matching the product and detail it names. With no specification in place, the first step sits with your designer or fire engineer, not with us. If you have unsealed joints where partitions meet the slab and expanding foam used as fire stopping, we can put it right, whatever the surface. Searching for sealant specialists in Woodside? We’ve been sealing commercial buildings since 2005.
After a fit-out or new cabling in a London building, risers and ceiling voids are where open service gaps tend to be found. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Common questions from Woodside clients
Do you take on jobs in Woodside where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry.
Can you seal penetrations in a hotel in Woodside after a refit?
Yes, where the specification calls for fire-rated sealant. We match the product to the wall or floor and the services, and say if something other than sealant is needed.
Can you work while the building is occupied?
In most cases, yes. We phase the work so most of the building stays in use.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
How long will the new sealant last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.
Compartment walls and floors in Woodside
With tenants changing and fit-outs following, London buildings see service routes altered again and again. Where fire-rated sealant is specified, we install it to the tested detail under the building’s permit-to-work arrangements. Approved Document B is the English guidance that covers fire stopping around 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. Our part stays the same: the specified product, installed to its tested detail.
Tenant changes at centres like Whitgift Centre, 1.7 miles to the south-west of Woodside, often mean new services through walls between units. Hotels like Croydon Park Hotel, 1.4 miles to the south-west of Woodside, are refurbished in phases, and each phase can open up compartment walls.
Woodside is about 6 miles south of New Cross, in Greater London. Any commercial site in Woodside is covered, whether it’s a single job or part of a planned programme.

Nearby places we also cover include Ashburton (1 mile south), Addiscombe (1 mile south), Shirley Oaks (1 mile south-east), Monks Orchard (1 mile south-east) and Shirley (1 mile south-east) for service penetrations.

Local landmarks in Woodside
Locally, jobs take us to sites close to The Beehive pub, Oasis Academy Shirley Park and Ashburton Park. Woodside’s nearest station is Norwood Junction station, roughly 0.7 miles north-west of the centre. Other landmarks nearby include Whitgift Centre (1.7 miles south-west) and Crystal Palace Museum (2.2 miles north). Not far away are Bramley Bank and Duppas Hill.
How a job runs
Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. All of Greater London is in the ULEZ, and kerbside space in Woodside can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- We read the specification, drawings or penetration schedule you send and ask about anything unclear.
- On site, each opening is checked against the tested detail it is meant to follow.
- Anything that doesn’t belong in the opening, such as expanding foam or general-purpose filler, is removed.
- We fit the backing the detail asks for, to the stated depth.
- We apply the specified sealant to the depth and around the services as the detail shows.
- If an opening needs something other than sealant, we tell you instead of improvising.
Preparing the site
- Tell us what induction or permit system the site runs
- Send any specification or drawings in advance
- Agree which areas must stay open

Work for main contractors and building owners
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
What we can’t put right
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Construction that lacks the fire resistance the seal relies on
- Signing off or certifying a building’s fire stopping
- Fire doors, dampers or other fire safety equipment
Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we will tell you honestly.
What we seal
- Joints between fire-resisting walls and floors
- Service gaps in risers
- Cable penetrations
- Linear gaps at wall heads
- Small duct penetrations where the tested detail allows
- Pipe penetrations
Different surfaces, different methods
Risers and ceiling voids
Voids hide a lot of unsealed openings. We work through the areas on your schedule methodically.
Small ducts
Some fire-rated sealant details cover small ducts. Bigger ducts and fire-resisting ductwork are normally handled with other products, and we’ll say if that applies.
Site staff or a sealant specialist?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
