Facade sealing for commercial buildings in Crowborough
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. We work on window and door perimeters, cladding panel joints and stone and brick facade joints, and the usual reasons a site gets in touch are sealant pulling away from frames or panels and draughts around frames and panels. One point of contact handles commercial sealant work in Crowborough from the first photos to the final walk-round, whether it’s one building or several.
Construction in a town such as Crowborough is often smaller schemes: a few new flats, a school extension, a refurbished unit. The perimeter and facade joints on a small scheme need the same sizing and preparation as on a big one.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Mastic packages on Crowborough sites
The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. Crowborough is about 33 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
For contractors at a school such as St Marys Catholic Primary School, sealing has to be finished before term starts. With historic properties like Groombridge Place (to the north of Crowborough) in the area, refurbishment work often meets old masonry that needs compatible sealants. Units on estates such as Crowborough Business Park (0.6 miles north of Crowborough) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

How the job changes by surface
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. We tell you if the fix is a roofing or metalwork job rather than a reseal.
Cladding panel joints
On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them.
When it isn’t the sealant
Some faults sit outside our scope, and we say so rather than covering them up:
- Cracked or spalling substrates that need repair before sealing
- Installing or repairing glazing systems
- Joints too narrow for the movement they take, which need redesign
If you are not sure, just speak to us on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.
Joints and surfaces we work on
- Coping and flashing joints
- Stone and brick facade joints
- Shopfront frames
- Window and door perimeters
- Cladding panel joints
- Perimeter joints where frames meet the structure
Why it’s worth doing now in Crowborough
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, so the real damage is often some distance away. For businesses and landlords in Crowborough, a tidy, sound joint also matters for appearance. Fresh sealant makes a building look maintained.
What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a fixed quote when you’re ready.

When to bring in a specialist
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Questions about Crowborough
Can you keep pace with our programme in Crowborough?
Yes. The mastic is planned around your key stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Is Crowborough Business Park, near Crowborough, within your area?
Yes. We cover Crowborough and the area around it, including industrial estates, business parks and retail parks such as Crowborough Business Park. Send details of the unit and the work through our quote form for a quick quote.
Should we check old sealant for asbestos?
It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, and we’ll ask to see it. If asbestos is suspected, work stops until it is tested.
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.
Do you take on small jobs?
Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you replace windows or glass?
No. That work needs a glazing specialist. What we seal are the joints around frames and panels.
Is it okay to overlay old mastic?
No. New sealant won’t hold on old sealant, so the old bead is cut away. Nothing else gives a bond that lasts.
Owners, agents and contractors
Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.
