Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Why deal with it now?
A quick bead over a damaged joint can get an area past inspection, but it won’t last. Sealant can’t grip a contaminated or existing bead. We cut out and redo the joint properly. Around Horton Kirby, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we will quote for the lot.
There’s no price list, since every building and every scope is different. Call for a quote and we will price your job on its own details.
What you get with us
- Colour options checked against the specified product
- Public liability insurance in place
- One phone line for London, the South East and Scotland
- Old sealant cut out, never sealed over

Construction mastic in Horton Kirby, done properly
The programme rarely stands still, so the mastic package has to flex with it. We agree a sequence at the start and adjust it as the site manager releases areas and we don’t seal before other trades have finished in an area. That keeps the work right first time and saves rework. We work on brick and block movement joints, floor and skirting junctions and internal decorators’ caulk, and the usual reasons a site gets in touch are oversized or tapered gaps around new frames and missed perimeter joints on a new elevation. Whoever orders the work in Horton Kirby, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
In the countryside around places like Horton Kirby, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Site staff or a sealant specialist?
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
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.

FAQs: Horton Kirby
Can you work on a hospital site such as Darenth Park Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Will you take on work at estates like Mills Trading Estate, close to Horton Kirby?
Yes. Estates, retail parks and business parks around Horton Kirby, Mills Trading Estate among them, are all within reach. To start, just give us a call on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Do you take on multi-site work?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Do you guarantee new-build sealant work?
Each package is signed off with a 12-month workmanship guarantee. Damage by others after we have finished isn’t covered.
Can you come in just for snagging?
Yes, we can. Share the list and photographs, and a fixed quote follows, then clear it to your programme.
Will you stick to the specified products?
Specification first, then the maker’s instructions. Preparation, backing and depth follow the product guidance.
Mastic packages on Horton Kirby sites
The South East is one of the drier 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. Central London is about 16 miles from Horton Kirby. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

For a contractor working at a hospital such as Darenth Park Hospital, 3 miles to the north of Horton Kirby, perimeter and facade sealing is planned around patients and deliveries.

What else we do in Horton Kirby
Common problems we fix in Horton Kirby
A joint without backing rod or bond-breaker often fails early. Fixed to three faces, the sealant rips the first time the joint opens, so depth is controlled with backing rod or bond-breaker tape.
Things that normally lead to an enquiry:
- Sanitary sealant damaged by following trades
- New external sealant already peeling away
- A mastic package split between trades with no clear owner
- Mastic snags holding up handover
Units on estates such as Mills Trading Estate (0.7 miles north of Horton Kirby) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
What to look for in a quote
- Their pre-qualification and accreditations
- Do they follow the manufacturer’s priming guidance?
- How they’ll work around occupants
- Will CSCS-carded applicators be on site?
When it isn’t the sealant
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Joint design decisions that belong to the architect or engineer
- Damage to finishes by other trades after we have sealed
- Glazing units that are cracked or misted
If you are not sure, just call 01277 525 020 or send details through our quote form and we’ll give you a straight answer before you book.
Surfaces we seal

How the job changes by surface
Fire-rated sealant where specified
Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services, and we will tell you if the detail calls for something else. Tell us what records you need and we will confirm with the quote.
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Each joint is prepared, sealed and finished with a neat tooled line, and any bath is loaded with water first where that’s the agreed method.
