Need facade sealing in Rownhams?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Different surfaces, different methods

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. We seal those perimeter joints.

Cladding panel joints

On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them.

Facade sealing for commercial buildings in Rownhams

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. We work on perimeter joints where frames meet the structure, cladding panel joints and stone and brick facade joints, and what we are called in for most is weathered joints at frame-to-structure perimeters and leaks at window and door perimeters. Whoever orders the work in Rownhams, the brief is usually the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

For a contractor on a smaller site near Rownhams, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, call 01277 525 020 or email us and we will come back to it.

Building owners, agents and FMs in Rownhams

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • The total length or number of joints
  • Whether the work must be split into stages
  • How accessible the joints are
  • Induction, permit and paperwork requirements

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

What to include in your enquiry

A good diagnosis starts with the right details. Let us know:

  • Any dates the work must fit around
  • Approximate linear metres or a joint schedule
  • The asbestos register, for older buildings
  • Any specification or named product

To get a fixed quote, speak to us on 01277 525 020 or use the quote form. You can also send details through our quote form.

When to call us in Rownhams

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.

Any of the following is a good reason to get the joints checked over:

  • Unsightly perimeter sealant on a visible elevation
  • Old perimeter mastic that has dried out
  • Leaks at window and door perimeters
  • Facade joints cracked through the middle

Building work at universities like University of Southampton, 2.8 miles to the south-east of Rownhams, is often timed for the summer, mastic included.

Questions to ask before you book

  • Their public liability cover
  • How the joint faces will be prepared and primed
  • What site paperwork they can supply
  • Health and safety accreditation such as CHAS

Facade sealing around Rownhams: how the place shapes the job

Rownhams lies within about 3 miles of the sea. 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. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.

When units on a site such as Kingfisher Business Park, 1.1 miles to the north-east of Rownhams, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. Further education sites such as Richard Taunton Sixth Form College, 2.3 miles south-east of Rownhams, are extended and refurbished from time to time, with mastic often programmed into the summer break.

Rownhams is about 3 miles north-east of Totton, in Hampshire. Across the SO16 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Across Hampshire, 723 places are covered, Rownhams among them.

Work on facade joints is covered throughout SO16, for business premises of every kind. For a building on Rownhams Way, Horns Drove and Rownhams Close or nearby, send details and we will quote for facade joints.

Why it’s worth doing now in Rownhams

Topping up a failed joint typically buys very little time. A full cut-out and fresh bead is the repair that holds and avoids repeat call-outs. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Why appoint us

  • Joints cleaned back to sound surfaces
  • CHAS accredited contractor
  • Matching to RAL references, product permitting
  • Workmanship guaranteed for 12 months

Our process

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a site in Rownhams, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.

  1. We plan access and the order of elevations with the client.
  2. Weather and temperature are checked against the product’s limits.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Send any specification or drawings in advance
  • Tell us what induction or permit system the site runs
  • Send your site hours and access windows

Ask for a quote

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, call the office on 01277 525 020 or send details through our quote form.

FAQs: Rownhams

Can you work on a hospital site such as Princess Anne Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Is Rownhams too far out for you?

Not at all. Rownhams is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Will you check whether the sealant is causing the leak?

Yes. We look at the perimeter sealant and tell you whether it has failed before quoting. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Do you run new sealant over the existing bead?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.

Can one quote cover more than one building?

Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Which sealant do you use on facades?

Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Some joints call for hybrid, PU or polysulphide instead, as the specification or substrate requires.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.
