About our commercial sealant contractors in Catslip
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and in an occupied building failure typically announces itself as a stained ceiling or an unhappy tenant. We’re commercial sealant applicators for FMs, managing agents, landlords and contractors with sites in Catslip. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. Most enquiries involve frame sealant that has cracked, shrunk or pulled away and expansion joints with the sealant torn out, on kitchen worktops and splashbacks, movement joints in walls and floors and external facade joints. Most enquiries from Catslip start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
The most common commercial job in Catslip is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
Business units in the countryside around places like Catslip are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials, and a sealant colour that suits the building’s character is often part of the brief.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Surface by surface
Movement joints in walls and floors
Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. When the seal fails, debris gets in and the joint stops working. The joints are resealed using a sealant matched to the movement and any traffic.
Fire-rated seals where specified
Fire-rated sealant is only one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services and gaps, and we will tell you if the detail calls for something else.
What Catslip’s businesses ask us to seal
Catslip is in the South East, one of the UK’s drier regions. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings. Central London is about 38 miles from Catslip. This part of the South East is dense with business parks and out-of-town offices. Multi-site occupiers here often want one sealant contractor across all their buildings.
For tenants and agents on sites such as Vanalloys Business Park (2.3 miles south-west of Catslip), office fit-outs, reception joints and window perimeters are the usual sealant work. Premises within reach of Henley-On-Thames station, 4.4 miles to the south-east of Catslip, often have busy frontages where joints are seen by everyone passing.

Questions about Catslip
Can you supply sealant in our brand colour for a site in Catslip?
Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Send colour references or photos and we’ll confirm what’s available for the product.
Is Catslip off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Is your work guaranteed?
The work is guaranteed for 12 months. Should anything we did fail within that period, let us know.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Will you just go over the old sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
What site paperwork can you provide?
Let us know your requirements when you ask for a price. From you, we’ll need the asbestos information for older buildings and any site rules.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
After the work
Your facilities or cleaning team can help the joints last. Share these points with them:
- Look at the sealant around anything that has been moved or replaced
- Report cracked or peeling sealant early
- Add sealant to the planned maintenance inspection list
- Don’t let cleaning or traffic back on before the cure time is up
Let your cleaning contractor know what’s new. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces; a mild cleaner is all most joints need.
A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.

How a job runs
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes anything from part of a day on a short run of joints to several weeks on a large phased package, and we clear our waste as we work.

Advice
Leave it or put it right?
A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. Often the fitting is sound and the joint is the only thing letting it down. Resealing typically costs far less than renewal, though we’ll tell you honestly if the element itself is the problem. Converted and older buildings near places like Catslip tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
A quote for sealant joints depends on quantities, condition and access, plus any specification you’re working to. Call for a quote.

When to call us in Catslip
In wet areas the enemy is usually mould rather than movement. Damp, harsh cleaning products and poor ventilation let mould take hold inside the bead, and once established it rarely cleans out. Replacement with a sanitary anti-mould silicone is the lasting answer.
Clients normally get in touch after noticing something like this:
- Layers of sealant, all of them failing
- Damp patches where an external joint has failed
- Black mould through washroom sealant that won’t clean off
- Untidy joints in a reception, shop floor or lobby
A hotel such as The White Hart Hotel, 0.5 miles west of Catslip, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.
