Your questions answered
Can you take on a job at a hospital such as Ticehurst House Hospital?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Is Birchett's Green off your patch?
No. Places such as Birchett's Green are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we will plan around them. Our office runs Monday to Friday, 8am until 5pm.
Can you work while the building is occupied?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
Do you take on mastic snagging only?
Yes. We clear snags by redoing joints rather than patching them.
Does weather matter for sealant work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Do you guarantee new-build sealant work?
It carries a 12-month guarantee on our workmanship. We’re also fully insured for public liability.
Construction mastic for commercial buildings in Birchett's Green
On refurbishments, the mastic package usually includes cutting out old sealant as well as sealing new work. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone and the asbestos survey is checked first on older stock. After that, the joints are prepared and sealed to the specification. If you have oversized or tapered gaps around new frames and inconsistent sealant finishes from plot to plot, we can help, whatever the surface. For commercial sealant work in Birchett's Green, you deal with one contact from quote to sign-off, whether it’s one building or several.
For a site near Birchett's Green, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photos and the programme let us give a fixed quote.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

What happens if it’s left?
Sealing over damaged or contaminated new joints might save a day, but it rarely lasts. Sealant can’t grip a contaminated or existing bead and the defect reappears in the defects period. We cut out and redo the joint properly. Converted and older buildings near places like Birchett's Green tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Aftercare for building managers
Regular inspection catches problems early. Specifically:
- Allow flexibility for external sealing in damp or cold weather
- Use the product the specification names
- Protect sealed areas from following trades
- Check frame gaps are within the sealant’s range before sealing
Tell the builders’ clean team which areas have new sealant. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.
Oversized gaps are a problem better caught early. Filling a wide gap with sealant alone sets up a failure. We flag them as soon as we see them.
New build and refits around Birchett's Green
Birchett's Green lies roughly 37 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand. Rainfall across the South East, Birchett's Green included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.
Older buildings in the area around Birchett's Green, such as Wadhurst Castle, 2 miles to the west of Birchett's Green, need care when sealed: the product has to suit soft or historic materials. For contractors refurbishing units at places like Parsonage Farm Business Centre, 1.8 miles south-east of Birchett's Green, the mastic covers cladding panels, roller-door and window perimeters. Hospital estates such as Ticehurst House Hospital, 1.1 miles to the south-east of Birchett's Green, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.

Surface by surface
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control.
Snagging before handover
The last pass before handover is where mastic snags are cleared. Snags are cleared room by room, cutting out damaged joints and resealing them properly.
Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
On site: what to expect
The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Birchett's Green, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- We start with the drawings, specification and programme.
