Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Look above ceilings when tiles are lifted for other jobs
- Brief every trade that openings they make must be sealed
- Treat an open penetration as a priority repair
- Foam or ordinary sealant is never a fire-seal repair
After the work, brief anyone else working in the area that the openings are now sealed. Any seal cut back for a new service needs reinstating to its tested detail.
On fit-outs, get the fire-stopping specification agreed before the services go in. The designer can then choose details that suit the services planned.
Fire stopping for commercial buildings in Sandwick
Where pipes, cables and other services cross a compartment wall or floor, the opening around them has to be closed so fire and smoke can’t move between compartments. Our job is fitting fire-rated and intumescent sealant at those service penetrations, and along linear gaps, where it is the specified product. Each seal follows the manufacturer’s tested detail rather than guesswork. If you have unsealed joints where partitions meet the slab and openings found when ceilings come down for a refit, we can help, whatever the surface. For commercial sealant work in Sandwick, you deal with one contact from quote to sign-off, whether it’s one building or several.
For a building near Sandwick, we plan fire-rated sealing so it’s finished in one visit where possible. Send the specification and photographs of the openings, with sizes if you have them.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Sandwick: questions and answers
How do the Scottish rules apply to fire-rated sealing in Sandwick?
Under Scotland’s non-domestic Technical Handbook (clause 2.1.14), service penetrations should keep at least the wall or floor’s fire resistance duration, using products tested for their end use. Design sits with the designer and the verifier; installation to the tested detail is our part.
Can you produce the fire-stopping design for a job in Sandwick?
No. Fire-stopping design and sign-off belong to the designer, principal designer, fire engineer or building control. Our part is installing the specified product to its tested detail, and telling you if the detail calls for something other than sealant.
Do you work to architects’ specifications?
Yes. Send it with your enquiry, and the quote will be based on it.
Can one quote cover more than one building?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Are you CHAS accredited and on Constructionline?
Yes. We’re CHAS accredited and a Constructionline member, which helps with supplier vetting.
Is Sandwick in your area?
Yes. Sandwick is in our area, within our coverage of Greater London, South East England and Scotland. For a quote, ring 01277 525 020 or use the quote form.
Is it fine to apply new sealant on top of old?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

We install what’s specified, to the product’s tested detail.

Diagnose, treat, sign off
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. For work around Sandwick, we aim for one trip, so photographs, sizes and a full list matter. Outside work also needs a suitable weather window.
- 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.
- Foam, ordinary sealant and debris come out.
- Backing and fire-rated sealant are installed to the detail and tooled.
- Anything outside the detail is reported to you rather than sealed.
Preparing the site
- Send your site hours and access windows
- Send asbestos survey details if the building is pre-2000
- Point out parking and an unloading spot

Building owners, agents and FMs in Sandwick
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sandwick can form part of a wider programme.
Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Sandwick. Several sites can go on one quote, which keeps the paperwork simple.
Doing it in-house
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Why it’s worth doing now in Sandwick
Fire stopping is a regular point raised at inspections and handover. Late discoveries can delay handover while openings are reopened and resealed. For buildings near Sandwick, dealing with all the failing joints at once saves return trips. Send photographs and we’ll quote for everything together.
The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
