About our facade sealing in Avisford

Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces. If you have perimeter joints where frames meet the structure and cold air coming in at window perimeters, we can put it right. One point of contact handles commercial sealant work in Avisford from the first photos to the final walk-round, for single jobs and planned programmes alike.

Construction in and around smaller places such as Avisford is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

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

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints too narrow for the movement they take, which need redesign
  • Installing or repairing glazing systems

If you’re not sure, just call 01277 525 020 or email us and we’ll give you a straight answer.

What we seal

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

General trades versus a specialist

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

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.

Building owners, agents and FMs in Avisford

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Avisford can sit alongside others in a wider programme across West Sussex.

When to call us in Avisford

A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back and rips when the facade moves.

If one of these sounds familiar, it’s time for a closer look:

  • Draughts around frames and panels
  • Discoloured or dirty facade joints
  • Water coming in around window frames
  • Weathered joints at frame-to-structure perimeters

When units on a site such as Tokar Industrial Park, 0.8 miles south of Avisford, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

What to look for in a quote

  • Will RAMS and insurance details be available?
  • Who will actually carry out the work
  • How the joint faces will be prepared and primed
  • Their public liability cover

Questions to ask before you appoint anyone

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Rural sites near Avisford may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. The new sealant goes in and is tooled firmly onto both faces.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Point out parking and an unloading spot
  • Send your site hours and access windows

Advice

Sites and facades in and around Avisford

A 2-mile radius around Avisford takes in a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Avisford lies roughly 50 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.

Projects at schools like Walberton and Binsted CofE Primary School work to term dates, so mastic is programmed tightly. Hotels like Avisford Park Hotel, less than half a mile west of Avisford, rarely close for long, so refurbishment mastic is phased floor by floor.

Quoting for work in Avisford

Each job is priced on its own details. The main factors are:

  • Quantities, in metres or numbers
  • The size and state of each joint
  • Distance, for remote addresses
  • Any access equipment needed

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Before you send an enquiry

However big the job, these details speed things up:

  • When you need the work done
  • Any specification or named product
  • The postcode of the building
  • The asbestos register, for older buildings

Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or send details through our quote form.

Common questions from Avisford clients

Could you schedule work at a campus like University of Chichester (Bognor Campus) for the vacation?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is Avisford too far out for you?

Not at all. Avisford is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Will your applicators have CSCS cards?

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

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

Do we need an asbestos check before resealing?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder, and we will ask to see it. Suspect material is left alone until it has been tested.

Can you find out why a window is leaking?

Yes. We check the sealant joints and report what we find before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
