Construction mastic in East Harting, done properly
Buyers, tenants and clients notice sealant lines long before they notice the structure. Untidy or missed joints are among the commonest snag items. We seal so the snag list stays short. If you’re dealing with internal caulk splitting as the building dries out and external joints sealed in damp or cold conditions that are now failing, we can put it right. Most enquiries from East Harting start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
For a site near East Harting, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photos and the programme let us give a fixed quote.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

East Harting: questions and answers
Will you fit the mastic around our build programme in East Harting?
Yes. Send the programme and drawings, and we will plan the mastic to suit the stages. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Would you work within a site like Petersfield Community Hospital?
Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
When can you be on site?
Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
Do you cover East Harting?
Yes. East Harting is in our area and the rest of West Sussex, within our coverage of Greater London, South East England and Scotland. For a quote, call the office on 01277 525 020 or email a schedule or drawings.
Can you work plot by plot or floor by floor?
We follow the trades through the building. Each plot, floor or elevation is sealed when it’s ready.
How long does a job like this take?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
Are you insured?
Yes. We’re fully insured, including public liability cover.
How the quote is worked out
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Distance, for remote addresses
- The site’s rules and procedures
- Any access equipment needed
- Specialist products, such as fire-rated or hygienic sealants
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote once you have the details.
Details that help us quote
However big the job, the same details help:
- How the joints are reached, and at what height
- When you need the work done
- Drawings or a marked-up plan, if available
- The site address and postcode
Need a figure for a tender or a budget? Send the scope and any drawings, and we will return a fixed quote that you can work with. If you have questions first, speak to us on 01277 525 020 or send photos by email.
Different surfaces, different methods
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line.
External facade and movement joints
External movement joints often need primer, depending on the substrate. We prime where the manufacturer specifies and work only when conditions suit.
Why deal with it now?
Getting the mastic contractor involved early pays off. We can check joint widths, flag frames with gaps that won’t seal and confirm products against the specification, which avoids last-minute problems. Called in at the end, the same issues surface during handover. Converted and older buildings near places like East Harting tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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.
Facades, frames and programmes in East Harting
East Harting lies roughly 49 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. 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.
Historic houses such as Uppark (to the south-west of East Harting) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. When a school such as Harting CofE Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. For a contractor working at a hospital such as Petersfield Community Hospital (4.1 miles north-west of East Harting), perimeter and facade sealing is planned around patients and deliveries.
