Fire stopping for commercial buildings in Picketts Lock
Opened ceilings and riser doors often reveal service openings nobody sealed. 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. We work on cable penetrations, joints between fire-resisting walls and floors and pipe penetrations, and the usual reasons a site gets in touch are unsealed penetrations discovered above suspended ceilings and old intumescent sealant that has split away. Whoever orders the work in Picketts Lock, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Fit-outs and M&E works in London buildings often leave service penetrations open behind ceilings and in risers. Fire-rated sealant goes in where it’s the specified item; where a collar, wrap or batt is called for instead, we flag it.
We sign every job 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.

Where services cross fire walls in Picketts Lock
The area within 2 miles of Picketts Lock holds several hotels. Hotels are divided into compartments, and refurbishments that add pipes and cables through bedroom and corridor walls leave gaps to close. The 2 miles around Picketts Lock include seven care or nursing homes. Care homes rely on fire-resisting walls and floors, and maintenance work that breaks through them leaves openings to seal. We install fire-rated sealant to the tested detail where it is specified.
Residences at universities like University of Portsmouth Walthamstow Campus, 3 miles to the south of Picketts Lock, have compartment walls that must be resealed whenever services change. For a building such as All Saints' Church, new heating or data runs are the usual reason penetrations need sealing. On a site such as Dominion Business Park (0.5 miles west of Picketts Lock), every fit-out that runs new services through a compartment wall leaves penetrations to seal with the specified product.

Honest limits

- Gaps in walls that were never built as compartment walls
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we will say what we think.

FAQs: Picketts Lock
Can you work in a care home near Picketts Lock with residents in?
Yes. We work around residents’ routines, a room or two at a time. Tell us about any infection-control or safeguarding requirements and we will work to them.
Is a hospital such as North Middlesex University Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is any job too small?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Can weather delay the job?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
What will the job cost?
Every job gets its own fixed quote. For yours, call the office on 01277 525 020 or send details through our quote form.
Do you have third-party installer accreditation for fire stopping?
No. We don’t hold a third-party fire-stopping installer certificate. Our credentials are CHAS accreditation, Constructionline membership and CSCS-carded applicators, and we are fully insured. If your contract requires third-party installer certification, we are not the right fit for that package.
Will you write the fire-stopping specification?
No. Deciding what is needed sits with the designer, fire engineer and building control. Our role is fitting the specified fire-rated sealant, following the maker’s tested details.
From enquiry to sign-off
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We start with your penetration schedule, drawings or specification.
- We plan the sequence of floors, risers and voids with you.
- Each opening is checked for wall or floor type, service, gap and depth.
- Unsuitable material is removed and the opening cleaned.
- The specified backing and sealant go in to depth and are finished neatly.
- Anything outside the detail is reported to you rather than sealed.
Before we start on site
- Tell us your opening times and when work is allowed
- Agree which areas must stay open
- Make sure the joints can be reached
Get a fixed quote
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to give us a call on 01277 525 020 or email the details over with what you know.

What affects the price in Picketts Lock
These are the things that shape the price:
- Backing rod, priming and other preparation
- How much there is to seal
- The product specified
- Working within restricted access windows
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.
What we need to price the job
A few photographs plus some basic facts will normally do. Please tell us:
- Any dates the work must fit around
- Rough lengths or quantities, or drawings if you have them
- The postcode of the building
- Asbestos survey details if the building is older
Photos, drawings or a schedule of the joints and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.
General trades versus a 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.
Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

What else we do in Picketts Lock
Maintenance after handover
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Make fire stopping part of every scope that crosses a fire-resisting wall
- Settle who seals which penetrations at the start of a project
- File the specified details where the next contractor can find them
- Ask which product is in place before decorating
Don’t patch a fire-rated seal with anything outside its tested detail. Repairs need the same product and detail as the original, or a new specification from the designer.
Regular walk-rounds of service areas are worth the time. Catching a damaged seal early keeps the fix small compared with dozens found at once.
