How we handle construction mastic in Harbourland
External mastic depends on the weather in a way most internal trades don’t. Cold or damp mornings, frost and condensation on frames can all hold external sealing up, so we plan elevations with the forecast and the programme in mind. Internal areas can typically carry on while the outside waits. We work on floor and skirting junctions, sanitary and kitchen joints and window and door perimeters, and the usual reasons a site gets in touch are a mastic package split between trades with no clear owner and a long mastic snag list close to completion. A single leaking joint is often how a building in Harbourland first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a site near Harbourland, 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 photos and the programme and we’ll 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’re clear about what is covered before work starts.

Common problems we fix in Harbourland
Frames installed with uneven gaps make perimeter sealing harder. Sealant has a range of joint widths it can cope with and gaps beyond it need packing or adjusting by the frame installer. Better to raise it at the start than seal a joint that’s bound to fail.
Common reasons buildings call us in:
- Sealant knocked or painted over by other trades
- Oversized or tapered gaps around new frames
- A long mastic snag list close to completion
- Cracks opening in caulked internal joints
For a contractor at a hotel such as The Bull Hotel, 1.5 miles to the south-west of Harbourland, the mastic often has to be finished before a reopening date.

FAQs: Harbourland
Is a smaller place like Harbourland outside your area?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Do you take on work at healthcare sites like KIMS Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Does the weather affect the 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.
Which sealant will you use?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
What joints do you seal on a new build?
External perimeters and movement joints, internal caulking where specified, sanitary and kitchen joints, plus snagging, all priced as one package.
What accreditations do you hold?
CHAS and Constructionline are both in place, and our applicators hold CSCS cards. Public liability insurance is in place.
Can you quote from photographs?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Facades, frames and programmes in Harbourland
There are a number of hotels within about 2 miles of Harbourland. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades. Rainfall across the South East, Harbourland 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, which is why external dates are agreed with the site manager.
For contractors at a college like MidKent College Maidstone Campus, 2.4 miles to the south-west of Harbourland, perimeters and internal sealant are timed for the holidays. On a healthcare site such as KIMS Hospital, 0.9 miles to the south-east of Harbourland, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Owners, agents and contractors
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Harbourland can form part of a wider programme across Kent.
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Surface by surface
External facade and movement joints
Movement joints in the facade are sealed with a product suited to the expected movement. Depth is controlled with backing rod so the bead bonds to two sides only.
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s paintable and suits gaps that don’t move, and we use a flexible sealant where there’s movement.
What sets the cost
To price the job, we consider:
- Backing rod, priming and other preparation
- Access and working height
- How much there is to seal
- How much existing material needs removing
There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
Sending details for a quote
To price the job accurately, we need to understand the site. Useful things to include:
- Photos of the joints, close up and from further back
- When you need the work done
- How the joints are reached, and at what height
- Whether an asbestos survey exists
A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or ring 01277 525 020 or email the details over if you’d rather talk the job through.
