About our construction mastic in Hundred Acres
Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list and clearing them late eats into the handover window. Our aim is joints that pass at the first inspection, area by area through the programme. We work on sanitary and kitchen joints, window and door perimeters and floor and skirting junctions, and the usual reasons a site gets in touch are missed perimeter joints on a new elevation and a long mastic snag list close to completion. Whoever orders the work in Hundred Acres, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Conversions of older rural buildings near smaller places such as Hundred Acres bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Why act early in Hundred Acres
A cheaper sealant can look like an easy saving on a large package. A failed joint in the defects period costs far more than the product difference and external joints are where it shows first. Where an alternative is genuinely suitable, we’ll say so. One visit to deal with every failing joint makes more sense than several trips to a place like Hundred Acres. Send photos of each area and we will quote for the lot.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
Why us?
- Specification-led, product-correct work
- Colour agreed before work starts
- Colours chosen to suit frames, cladding or finishes where possible
- One phone line for London, the South East and Scotland

When to call us in Hundred Acres
Shrinkage and settlement in the first months put new joints under strain. Materials lose construction moisture and shrink. Picking a flexible sealant where there’s movement keeps snags down.
Typical triggers for a call:
- Different trades sealing to different standards
- External joints sealed in damp or cold conditions that are now failing
- Caulk cracking where joints are moving more than expected
- Window and door perimeters that won’t pass inspection
Hotels like The Old House Hotel (to the west of Hundred Acres) rarely close for long, so refurbishment mastic is phased floor by floor.
Comparing quotes
- Will CSCS-carded applicators be on site?
- How the existing material will be dealt with
- Proof of insurance
- Health and safety accreditation such as CHAS
General trades versus a specialist
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
How the quote is worked out
These are the things that shape the price:
- The product specified
- Working within restricted access windows
- The site’s rules and procedures
- Whether old sealant has to be cut out first
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.
Details that help us quote
A good diagnosis starts with the right details. Tell us:
- Asbestos survey details if the building is older
- Approximate linear metres or a joint schedule
- Your programme or deadline
- A wide shot and a close-up of the area
Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, speak to us on 01277 525 020 or send details through our quote form.
What the job involves on each surface
Internal decorators’ caulk
Caulking is often done in a hurry by whoever’s on site. A neat, consistent caulk line makes the decorators’ job quicker and reduces snags.
Snagging before handover
Damaged, missed or untidy joints make up most snag lists. Snagging can be included or priced separately, depending on what suits the programme.
Construction mastic around Hundred Acres: what changes locally
At about 62 miles from central London, Hundred Acres is within reach of the capital. 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. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
Extensions at sites like Knowle Hospital (2.4 miles south-west of Hundred Acres) usually sit beside working departments, and the mastic follows strict access rules. Recladding or extending a unit at a site like Knowle Village Business Park, 2.5 miles south-west of Hundred Acres, brings panel joints and frame perimeters into the programme.

Hundred Acres: questions and answers
Do you take on work at healthcare sites like Knowle 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 Hundred Acres off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you use the sealant named in the specification?
We use the product the specification names. Any suggested alternative is put to you before anything changes.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
How do you choose the sealant?
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.
Is colour matching possible?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Will you just go over the old sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
