How we handle facade sealing in Kimpton
Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. Most enquiries involve leaks at window and door perimeters and perimeter sealant that has split or peeled away, across window and door perimeters, cladding panel joints and shopfront frames. A single leaking joint is often how a building in Kimpton first comes to us: we look at the rest while we are there and tell you what we find.
For a site near Kimpton, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Diagnose, treat, sign off
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. For a building around Kimpton, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- We start with photos, drawings or a visit to see the joints and agree access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full.

Why deal with it now?
Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. Halls, stores and units around places like Kimpton may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.
The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Signs you need facade sealing in Kimpton
Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, and cracks or adhesion loss follow.
Look out for the following:
- New sealant peeling off old mastic
- Cold air coming in at window perimeters
- Gaps between rainscreen or cladding panels
- Discoloured or dirty facade joints
With historic properties like Shaw's Corner, 1.8 miles to the south-east of Kimpton, in the area, refurbishment work often meets old masonry that needs compatible sealants.

FAQs: Kimpton
What paperwork can you provide for a job in Kimpton?
We’ll confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Can you work to our programme on a site in or near Kimpton?
Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you seal facades in winter?
Wet joints or temperatures outside the product’s range mean waiting. The programme allows for it and we tell you if the forecast changes things throughout the job.
Can the building stay open while you work?
In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
When can you be on site?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Commercial clients in Kimpton
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
General trades versus a specialist
Certain joints really need a specialist: for example 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.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Sites and facades in and around Kimpton
Kimpton sits in one of the drier corners of the country, the South East. 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. Kimpton lies roughly 26 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.
When a school such as Kimpton Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
