Commercial sealant contractors in Hounsdown

How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Primer is used wherever the manufacturer calls for it on that surface and the joint depth is controlled with backing rod. If you have hardened, chalky sealant on south-facing or exposed elevations and a top-up bead over failed sealant, now lifting, we can help, whatever the surface. Whoever orders the work in Hounsdown, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

A lot of what we do in Hounsdown is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

Sealant jobs for businesses in a place the size of Hounsdown are often best grouped: frontage, staff facilities and window perimeters on one booking. Fewer visits means less disruption to trading, and where colour matters on the frontage, we will confirm what’s available for the product.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Shops, offices and hotels in and around Hounsdown

Hounsdown sits close to the coast, within about 2 miles. Exposed frontages near the sea are hard on sealant, so the product has to suit the weather as well as the look. We choose a product rated for the exposure, then confirm the colours available for it. Rainfall across the South East, Hounsdown included, is lower than in many parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.

For premises near Totton station, which lies north-east of Hounsdown, footfall is part of the plan: work is phased so shops and offices keep trading. For tenants and agents on sites such as Rushington Business Park, less than half a mile to the north of Hounsdown, office fit-outs, reception joints and window perimeters are the usual sealant work. A hotel such as The Station Hotel (1.2 miles north-east of Hounsdown) shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

Questions we are asked in Hounsdown

Is Rushington Business Park, near Hounsdown, within your area?

Yes. Our area takes in Hounsdown and its surroundings, with estates and business parks such as Rushington Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Is a smaller place like Hounsdown outside your area?

Not at all. Hounsdown is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Is the old sealant taken out first?

The old bead is stripped out first. After that come cleaning, primer where needed, backing and the new sealant.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

When is resealing likely to be due?

Nobody can honestly give a figure in years, 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.

How a job runs

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. For a job in Hounsdown, the main thing is a clear picture of the work. You’ll then get a fixed price for the work.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

Getting the site ready

  • Send any specification or drawings in advance
  • Share your working hours and any access restrictions
  • For older buildings, check the asbestos register before work

For managing agents and facilities managers

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Why deal with it now?

Putting off a reseal typically moves the cost rather than avoiding it. Once water gets behind the seal, finishes and ceilings underneath are next, which brings decorators and flooring contractors into the repair. Dealing with it while the damage stops at the bead is the cheaper route. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

Pricing sealant joints depends on how many there are, their condition and the access. Call for a quote.

Different surfaces, different methods

Shop fronts and retail fit-outs

In retail, sealant is on show. Joints around counters, displays and shopfront frames have to look tidy as well as seal, often in a colour to suit the brand finish. We’ll confirm the colours available for the specified product.

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.

Honest limits

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Roof leaks that only look like a joint problem
  • Structural cracks or movement the joints weren’t designed for
  • Old mastic that tests positive for asbestos

Not sure which it is? You can ring 01277 525 020 or email a schedule or drawings and we will tell you honestly before you book.

Surfaces we seal

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

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
