Construction mastic in Purbrook Heath, done properly
Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone, and on older buildings we ask for the asbestos survey before disturbing anything. New and existing joints then get the same preparation. If you have snag items on joints that need redoing before handover and missed perimeter joints on a new elevation, we can help, on window and door perimeters, brick and block movement joints and floor and skirting junctions alike. Facilities teams, main contractors and managing agents in Purbrook Heath tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Around smaller places like Purbrook Heath, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Quoting for work in Purbrook Heath
To price the job, we consider:
- How much there is to seal
- The site’s rules and procedures
- Working within restricted access windows
- The product specified
The specified product makes a difference, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Before you send an enquiry
We can often quote from photographs and a few details. Please tell us:
- Asbestos survey details if the building is older
- Your programme or deadline

Contractors’ notes for Purbrook Heath
Purbrook Heath is within about 2 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Purbrook Heath lies roughly 60 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and each scheme needs its mastic sealed to programme.
Older buildings in the area around Purbrook Heath, such as Warblington Castle, 4.2 miles east of Purbrook Heath, need care when sealed: the product has to suit soft or historic materials. When units on a site such as Oak Park Industrial Estate (2 miles south-west of Purbrook Heath) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Extensions at sites like Queen Alexandra Hospital, 1.4 miles south-west of Purbrook Heath, usually sit beside working departments, and the mastic follows strict access rules.

What sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Defective windows, doors or glazing units (the supplier or installer’s job)
- Oversized gaps that need packing or adjustment by others
- Designing joint widths or choosing the specification (that sits with the designer)
If in doubt, ring 01277 525 020 or send photos by email and we will say what we think.
Surfaces we seal
- Internal decorators’ caulk
- Window and door perimeters
- Floor and skirting junctions
- Cladding and panel joints
- Sanitary and kitchen joints
- Brick and block movement joints
How the job changes by surface
Kitchens and utility areas
Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.
Fire-rated sealant where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the manufacturer’s tested detail. Fire stopping design belongs to the designer and building control.
General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Diagnose, treat, sign off
We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. For a building around Purbrook Heath, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

What else we do in Purbrook Heath
Common questions from Purbrook Heath clients
Can you work at a site such as Oak Park Industrial Estate, by Purbrook Heath?
Yes. Our area takes in Purbrook Heath and its surroundings, with estates and business parks such as Oak Park Industrial Estate included. To start, just call 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Do you take on work at healthcare sites like Queen Alexandra Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Do you use the sealant named in the specification?
We work to the specification and the manufacturer’s installation guidance. Primers, backing and joint depth follow what the manufacturer sets out.
Are you CHAS accredited?
Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. We confirm any paperwork you need with the quote.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
Can you seal external joints in wet or cold weather?
Conditions have to suit the product before external work starts. Wet or cold joints cause adhesion problems so it’s better to wait.
Do you cover Purbrook Heath?
Yes. Sites across Purbrook Heath are covered, with one number for every area we cover.
Work for main contractors and building owners
If you look after buildings for someone else, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.
FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.
