Contractors’ notes for Locks Heath
With the shore within about 2 miles, Locks Heath counts as a coastal location. 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. Locks Heath is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team.
When a school such as Park Gate Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Hospital estates such as Fareham Community Hospital, 0.6 miles to the north-west of Locks Heath, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Units on estates such as Park Gate Business Centre (to the north of Locks Heath) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
Locks Heath is about 3 miles west of Fareham, in Hampshire. Anywhere in SO31, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed.

Whoever orders the work in Locks Heath, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

How the job changes by surface
Kitchens and utility areas
On commercial kitchen fit-outs, hygienic sealants are often specified. We follow the specification and seal to a smooth, cleanable finish.
Window and door perimeters
Gaps around frames have to be within the sealant’s range. Gaps outside the product’s range are raised with the site team.
Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Keep finished joints away from paint, plaster and scrapers
- Record the products used in the O&M file
- Ask for joint and product checks before the package is urgent
- Use the product the specification names
Brief the sparkle clean so they don’t scrape the new joints. Scrapers used on frames and worktops can nick or lift a new bead, so stick to soft cloths and gentle cleaners near sealant.
Snag items left to the last week put handover at risk. Clearing snags area by area spreads the work out.
When it isn’t the sealant
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Glazing units that are cracked or misted
- Oversized gaps that need packing or adjustment by others
- Rework caused by others damaging completed areas
Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
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.
Why act early in Locks Heath
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. Leave it late and they turn up on the snag list. For buildings in places like Locks Heath, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
