Facade sealing for East Hagbourne sites

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

Why it’s worth doing now in East Hagbourne

Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. Around East Hagbourne, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

Why us?

  • Colours chosen to suit frames, cladding or finishes where possible
  • Coloured sealants to suit the setting, where available
  • Our applicators hold CSCS cards
  • Workmanship guaranteed for 12 months

About our facade sealing in East Hagbourne

External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. If you are dealing with air leaks through failed facade joints and gaps between rainscreen or cladding panels, we can put it right, on coping and flashing joints, stone and brick facade joints and cladding panel joints alike. Looking for mastic applicators who cover East Hagbourne? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Construction in and around smaller places such as East Hagbourne 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.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Work for main contractors and building owners

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around East Hagbourne. Several sites can go on one quote, which keeps the paperwork simple.

When you manage a building on behalf of an owner, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Do you need facade sealing in East Hagbourne?

Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly, and movement soon pulls it away.

Look out for the following:

  • Water coming in around window frames
  • Gaps between rainscreen or cladding panels
  • New sealant peeling off old mastic
  • Sealant pulling away from frames or panels

When units on a site such as Market Place Shopping Centre (1 mile north of East Hagbourne) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Before you book anyone

  • Are they CHAS accredited or on Constructionline?
  • What level of public liability insurance do they hold?
  • What the guarantee covers, and for how long
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

How to choose a sealant contractor

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Replacing glass or failed glazing units
  • Damaged frames that need replacing
  • Joints whose design needs changing by the specifier

If in doubt, ring 01277 525 020 or send details through our quote form and we’ll say what we think.

Joints and surfaces we work on

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

How the job changes by surface

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather and need a durable external sealant.

Precast concrete panels

Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod, primed where the maker specifies.

Diagnose, treat, sign off

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. If others near East Hagbourne need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Getting the site ready

  • Tell staff and tenants when we will be in
  • For older buildings, check the asbestos register before work
  • Point out any areas we must not close

Questions we’re asked in East Hagbourne

Is East Hagbourne too far out for you?

No. Places such as East Hagbourne are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Can you work at a site such as Market Place Shopping Centre, by East Hagbourne?

Yes. We cover East Hagbourne and the area around it, including industrial estates, business parks and retail parks such as Market Place Shopping Centre. Send details of the unit and the work through our quote form for a quick quote.

Which sealant do you use on facades?

It depends on the joint, the substrate and any specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.

Can you work on upper floors?

That varies with the building and the access on offer. When you give us a call on 01277 525 020 or send photos by email, describe the access, and we’ll plan the work with you.

Can staff carry on working while you’re here?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Do you run new sealant over the existing bead?

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

Sites and facades in and around East Hagbourne

At about 50 miles from central London, East Hagbourne is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager.

Extensions at sites like Didcot Hospital, 1.1 miles to the north-west of East Hagbourne, typically sit beside working departments, and the mastic follows strict access rules. For contractors at a school such as Hagbourne Church of England Primary School, sealing has to be finished before term starts.

East Hagbourne is about 1 mile south of Didcot, in Oxfordshire. We cover commercial sites throughout East Hagbourne, whether it’s a single job or part of a planned programme. East Hagbourne is one of 423 places in Oxfordshire on our list. Oxford is covered too, some 11 miles away.
