Facade sealing for South Leigh sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

After the work

A few simple habits keep the new joints working:

  • Insist on a full cut-out when joints are renewed
  • Add perimeter sealant to planned maintenance checks
  • Brief window cleaners about newly sealed joints
  • Combine resealing with other works that need access

Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.

Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in.

How we handle facade sealing in South Leigh

Installing framed glazing systems isn’t part of our work. We handle the sealant joints that surround those elements: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. We work on perimeter joints where frames meet the structure, shopfront frames and cladding panel joints, and the usual reasons a site gets in touch are patch repairs that keep failing and hard, chalky sealant that no longer flexes. Whether you call it commercial sealant work, mastic application or joint sealing, the work in South Leigh is the same: the right product in a properly prepared joint.

Construction in and around smaller places such as South Leigh is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Surface by surface

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

Coping and flashing joints

Sometimes the coping or flashing itself has failed. We tell you if the fix is a roofing or metalwork job rather than a reseal.

Facade sealing around South Leigh: how the place shapes the job

At about 60 miles from central London, South Leigh is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. South Leigh is in the South East, one of the UK’s drier regions. 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.

Projects at schools like Wood Green School work to term dates, so mastic is programmed tightly. University estates such as Azad University in Oxford, 3.3 miles to the east of South Leigh, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. When a college such as Abingdon & Witney College: Witney Campus (2.5 miles west of South Leigh) builds or refurbishes, the mastic package usually has to fit around students and staff.

South Leigh is about 3 miles east of Witney, in Oxfordshire. If you are looking for facade sealing in South Leigh, we can help, as we do across Oxfordshire. South Leigh is one of 423 places we cover in Oxfordshire for facade joints. Our Oxford page has more on work in that area.

Questions about South Leigh

Is South Leigh off your patch?

No. Places such as South Leigh are covered as much as the big towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Could you schedule work at a campus like Azad University in Oxford for the vacation?

Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Can you handle several sites?

Yes. Several buildings can share a single quote, with one point of contact.

Will you quote for a small job?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

What type of sealant goes on window perimeters?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.

When can you be on site?

We are in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Can you just add new sealant on top?

No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.

What sets the cost

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

  • The size and state of each joint
  • The total length or number of joints
  • Whether the work must be split into stages
  • The site’s rules and procedures

A quote for facade joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

What we need to price the job

Whether it’s one area or a whole building, the same details help:

  • Approximate linear metres or a joint schedule
  • Access details, including height
  • Any specification or named product
  • Clear photos of the problem areas

For a fixed quote, give us a call on 01277 525 020 or send details through our quote form with the site address and an outline of the work. You can also send details through our quote form.

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around South Leigh can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. Product choice follows the joint’s movement and substrate.
  3. The existing bead comes out in full and the joint faces cleaned.
  4. Primer is applied where the maker specifies it.
  5. Rod goes in to fix the depth, then the joint is sealed and tooled.
  6. We go over the completed work with you before leaving.

Getting the site ready

  • Share your working hours and any access restrictions
  • Agree which areas must stay open
  • Send asbestos survey details if the building is pre-2000

Doing it in-house

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

Commercial clients in South Leigh

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.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.
