Our process

Inspect, seal, sign off: that’s the shape of every visit.

After the work

Keep the joints in good shape with a few simple steps:

  • Respect the cure time before reopening an area
  • Make sure ventilation in wet areas is switched on and working
  • Keep abrasive pads and scrapers off resealed joints
  • Add sealant to the planned maintenance inspection list

In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer. Your maintenance team can look at extract fans at the same time.

Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.

Should maintenance staff do it?

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.

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.

Questions about Purbrook Heath

Is a smaller place like Purbrook Heath outside your area?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you take on work at estates like Oak Park Industrial Estate, close to Purbrook Heath?

Yes. We cover Purbrook Heath and the area around it, including industrial estates, business parks and retail parks such as Oak Park Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Do you work for facilities managers and managing agents?

Yes. A large share of our work comes through facilities managers, managing agents and landlords as well as contractors. Tell us how you issue work and we’ll fit in.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Can one contractor look after sealant on all our buildings?

Yes, across South East England, Greater London and all of Scotland. One contact and one process for every building makes a portfolio easier to manage.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Commercial sealant contractors in Purbrook Heath: the local picture

The sea is no more than about 2 miles from Purbrook Heath. Buildings near the sea put their external joints through more driven rain, with salt air nearer the beach. Where a frontage needs a particular colour, the product still has to suit that exposure. Purbrook Heath is about 60 miles from central London. Business parks and retail centres are common around the capital’s motorway corridors. Firms with branches across the South East can use one contractor for every site.

Shops and cafés around stations like Cosham station, 1.9 miles south of Purbrook Heath, trade from early, so work is timed around them. A unit on an estate like Oak Park Industrial Estate (to the south-west of Purbrook Heath) usually has an office front, a trade counter and staff facilities with joints of their own. A business with units at Oak Park Industrial Estate and Parklands Business Park needn’t use two contractors for its sealant.

What the job involves on each surface

Facade and cladding joints

On a facade, a failed joint is often only visible close up. Photos from a closer viewpoint help us price.

Commercial kitchens and tea points

Gaps and ragged beads trap dirt that cleaning can’t reach. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.

For managing agents and facilities managers

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

When it isn’t the sealant

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:

  • Broken glass or blown double-glazed units
  • A dripping trap, valve or pipe behind a fitting
  • Old mastic that tests positive for asbestos

Not sure which it is? You can call 01277 525 020 or email drawings and photos and we’ll tell you honestly.

What we seal

  • Washrooms and tea points
  • Movement joints in walls and floors
  • External facade joints
  • Kitchen worktops and splashbacks
  • Window and door perimeters
  • Floor and threshold joints
