Facade sealing in Little Wittenham

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Site staff or a sealant specialist?

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

About our facade sealing in Little Wittenham

We are often asked to look at water coming in around frames. Very often the perimeter bead has cracked or lost its grip. If the evidence points away from the sealant, we say so before quoting. If you have failed seals around shopfront and entrance frames and patch repairs that keep failing, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Little Wittenham, that means joint design, primers and backing rod as standard.

Sites around smaller places like Little Wittenham can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photos and the programme and we will quote to suit.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When something else is needed

We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:

  • Arranging specialist high-level access, which is planned with the client
  • Movement beyond what any sealant can handle
  • Replacing glass or failed glazing units

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.

What we seal

  • Cladding panel joints
  • Stone and brick facade joints
  • Shopfront frames
  • Coping and flashing joints
  • Window and door perimeters
  • Perimeter joints where frames meet the structure

What affects the price in Little Wittenham

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Phasing around occupants
  • How much there is to seal
  • Site requirements such as inductions and permits
  • Location, for remote and island sites

What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

Details that help us quote

The more we know, the firmer the quote. Helpful details to send:

  • Where the site is, with the postcode
  • Any dates the work must fit around
  • Specification clauses that apply
  • Drawings or a marked-up plan, if available

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email a schedule or drawings to discuss it first.

Work for main contractors and building owners

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.

Whether you’re a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Common questions from Little Wittenham clients

Is Little Wittenham off your patch?

No. Places such as Little Wittenham are covered as much as the big towns. 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.

Would you work within a site like Abingdon Community Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can you look at water coming in around a frame?

Yes. We look at the perimeter sealant and tell you whether it has failed. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Do you provide access for facade work?

That varies with the building and the access on offer. Share what access exists or is planned when you send details, and we’ll agree the approach together.

Is old mastic on our building likely to contain asbestos?

In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. For work around Little Wittenham, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  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.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Arrange parking or a loading space
  • Tell us your opening times and when work is allowed

Ask for a quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Building and refurbishing in Little Wittenham

Little Wittenham is in the South East, one of the UK’s drier regions. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. Little Wittenham lies roughly 48 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme.

With historic properties like Brightwell Manor, 1.7 miles south-east of Little Wittenham, in the area, refurbishment work often meets old masonry that needs compatible sealants. Extensions at sites like Abingdon Community Hospital (to the north-west of Little Wittenham) usually sit beside working departments, and the mastic follows strict access rules. For contractors refurbishing units at places like Southmead Industrial Estate, 2.9 miles west of Little Wittenham, the mastic covers cladding panels, roller-door and window perimeters.

Surface by surface

Render and coated surfaces

Sealant can only hold as well as the render or paint beneath it. We remove flaking material so the bead bonds to a firm surface.

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.
