Construction mastic in Freshwater, done properly
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, with public liability insurance in place. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. The enquiries we see most involve window and door perimeters that won’t pass inspection and a mastic package split between trades with no clear owner, across sanitary and kitchen joints, floor and skirting junctions and brick and block movement joints. A single leaking joint is often how a building in Freshwater first comes to us: we look at the rest while we’re there and tell you what we find.
Conversions around smaller places like Freshwater often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.
Every job we finish is backed by a 12-month workmanship guarantee, in Freshwater as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Work for main contractors and building owners
Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
When to bring in a specialist
General builders and handymen seal joints, but it isn’t their main trade. 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.
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.
Your questions answered
Is Freshwater off your patch?
Not at all. Freshwater is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.
Does a coastal location like Freshwater affect which sealant is used?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.
Can fire-rated sealing at service penetrations be included?
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested details. The design and sign-off belong to the designer, fire engineer or building control.
Are you CHAS accredited?
We’re CHAS accredited and a Constructionline member, with CSCS-carded applicators. We are also fully insured, with five million pounds of public liability cover.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
Can you work to our specification?
The specification decides the product and flag anything that doesn’t look right for the joint. Specifications often reference BS EN 15651 or BS 6213.
Can you work plot by plot or floor by floor?
The programme sets the job. Share the release dates and we’ll match our work to them, sealing as areas become ready.
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Get the mastic subcontractor involved early in the programme
- Keep product details for future maintenance
- Protect sealed areas from following trades
- Stick to the specified sealant rather than a generic substitute
Record which products went where in the handover file. That helps the building owner maintain the joints later, and tells you what to reseal with. Tell us what records you need and we’ll confirm with the quote.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Filling a wide gap with sealant alone sets up a failure. We raise them during our first walk of the area.

What else we do in Freshwater
Why it’s worth doing now in Freshwater
Getting the mastic contractor involved early pays off. Early involvement means gaps, products and access are sorted before the programme bites rather than at the snagging stage. Called in at the end, the same issues surface during handover. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Quoting for work in Freshwater
To price the job, we consider:
- How much there is to seal
- Any access equipment needed
- Induction, permit and paperwork requirements
- Joint width, depth and condition
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.
Details that help us quote
However big the job, the same details help:
- The product your specification calls for
- When you need the work done
- The postcode of the building
- Anything awkward about access or site hours
Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to phone 01277 525 020 or send photos by email with what you know.
Building and refurbishing in Freshwater
Freshwater sits close to the coast, within about 1 mile. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, so we check the specified product suits the exposure before the first bead. Freshwater has plenty of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
School extensions, at buildings such as All Saints Church of England Primary School, typically run to the summer holidays, mastic included. Older buildings in the area around Freshwater, such as Mottistone Manor, which lies south-east of Freshwater, need care when sealed: the product has to suit soft or historic materials. Hotels like Albion Hotel, 1 mile to the south-east of Freshwater, rarely close for long, so refurbishment mastic is phased floor by floor.
Freshwater is about 5 miles south of Lymington, in the Isle of Wight. Any commercial site in Freshwater is covered, for single jobs and planned programmes alike. Freshwater is one of 125 places in the Isle of Wight on our list for mastic packages. There’s a separate page for Southampton, about 17 miles away.
Commercial sites across PO40 are covered for mastic packages. If your site is on Dall Square, High Street and The Square or close by, send details and we’ll quote for mastic packages. Nearby places we also cover include Easton (1 mile south-east), Colwell (1 mile north-west), Norton Green (1 mile north), Afton (1 mile south-east) and Totland (1 mile west) for mastic packages. Further afield, our area takes in Newport (10 miles east), Cowes (11 miles north-east), Shanklin (15 miles east), Ventnor (15 miles south-east), East Cowes (12 miles north-east) and Barton (10 miles east). Island and remote sites need extra planning, with travel, ferry crossings where needed and weather to allow for, so give the site location in your enquiry.
