How we handle construction mastic in Gatcombe
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, so applicators arrive when areas are genuinely ready. Sealing too early only means coming back once others have damaged it. We work on sanitary and kitchen joints, floor and skirting junctions and brick and block movement joints, and what we are called in for most is window and door perimeters that won’t pass inspection and existing joints on a refurb that need cutting out and resealing. A single leaking joint is often how a building in Gatcombe 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.
Construction in and around smaller places such as Gatcombe is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Mastic packages on Gatcombe sites
The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team.
For contractors at a college like HTP Apprenticeship College (2.6 miles north of Gatcombe), perimeters and internal sealant are timed for the holidays. For contractors refurbishing units at places like Mountjoy Industrial Estate (1.6 miles north of Gatcombe), the mastic covers cladding panels, roller-door and window perimeters.
Gatcombe is about 2 miles south of Newport, in the Isle of Wight. We cover commercial sites throughout Gatcombe, for single jobs and planned programmes alike. Our the Isle of Wight coverage takes in 125 places. There’s a separate page for Portsmouth, about 14 miles away.

Diagnose, treat, sign off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Gatcombe, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- We start with the drawings, specification and programme.
- Quantities are measured and a fixed price returned.
- The sequence is agreed with the site manager.
- Plots or floors are sealed as they’re handed over.
- Every joint is cleaned, set to depth and sealed with the specified product.
- After snagging, the work is handed over under our 12-month guarantee.

Advice
Should maintenance staff do it?
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
Different surfaces, different methods
Bathrooms, en suites and washrooms
Sanitary joints around baths, showers, basins and WCs need anti-mould sanitary silicone. Joints are cleaned, sealed and tooled neatly.
External facade and movement joints
Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.
What sets the cost
What shapes the price:
- The size and state of each joint
- How much there is to seal
- Specialist products, such as fire-rated or hygienic sealants
- Travel to remote or island sites
We don’t publish prices, since every building and every scope is different. Call for a quote and we will price your job on its own details.
What we need to price the job
We can often quote from photos and a few details. It helps to include:
- The product your specification calls for
- Access details, including height
- The postcode of the building
- Rough lengths or quantities, or drawings if you have them

FAQs: Gatcombe
Is Gatcombe off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.
Can work at a site such as HTP Apprenticeship College fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Are you fully insured?
Yes. We are fully insured, including public liability cover.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
How do you work with the site programme?
We seal plot by plot or floor by floor as areas are released. The sequence is agreed with the site manager at the start.
Why deal with it now?
A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects, especially externally. Where an alternative is genuinely suitable, we’ll say so. Older rural buildings around Gatcombe move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

When to call us in Gatcombe
Most mastic snags on new buildings come from sequencing rather than product. If sealant goes in before the last trades are through, it gets knocked, painted over or contaminated, so they end up back on the snag list.
What tends to prompt an enquiry:
- Sanitary sealant damaged by following trades
- Inconsistent sealant finishes from plot to plot
- External joints sealed in damp or cold conditions that are now failing
- Window and door perimeters that won’t pass inspection
On a healthcare site such as Whitecroft Hospital (0.6 miles north-east of Gatcombe), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Before you book anyone

- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Which product they’ll use, and why it suits the joint
- Health and safety accreditation such as CHAS
