Need facade sealing in Duns Tew?

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Note when each elevation was last resealed
  • Avoid patch repairs on failed facade joints
  • Check that rainwater leaves the facade the way it was designed to
  • Plan facade sealing alongside redecoration

Keep a note of which product went in and when. Future work can then match the product and colour without guesswork.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.

Facade sealing in Duns Tew, done properly

Managing agents and owners in Duns Tew ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. We work on shopfront frames, perimeter joints where frames meet the structure and coping and flashing joints, and the failures we are asked to look at most are new sealant peeling off old mastic and weathered facade joints that have lost their grip. A specialist sealant contractor works differently from a general builder: on jobs in Duns Tew, preparation and product choice get the time they need.

Construction in and around smaller places such as Duns Tew 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.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Quoting for work in Duns Tew

We price every job individually. The things that drive the figure:

  • How much existing material needs removing
  • Which sealant the job calls for
  • Travel to remote or island sites
  • The site’s rules and procedures

A quote for facade joints depends on quantities, condition and access, plus any specification you are working to. Ask us for a fixed quote.

Details that help us quote

A few photos plus some basic facts will normally do. Please tell us:

  • The type of building and who uses it
  • The postcode of the building
  • Photos of the joints, close up and from further back
  • Specification clauses that apply

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings that you can work with. If you have questions first, phone 01277 525 020 or email the details over.

When to bring in a specialist

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.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Duns Tew: questions and answers

Can the mastic package for our job in Duns Tew follow the site programme?

Yes. Send the programme and drawings, and we’ll plan the mastic to suit the stages. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Is Duns Tew too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and the quote will be based on it, flagging anything that needs clarifying.

Do you guarantee your work?

Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.

How do I request a quote?

You can use the quote form on this site; alternatively, call the office on 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.

Can you fit around our working hours?

Give us your site hours and any access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

Diagnose, treat, sign off

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For work around Duns Tew, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  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. We walk the finished joints with you before handing over.

Getting the site ready

  • Point out parking and an unloading spot
  • Point out any areas we must not close
  • For older buildings, check the asbestos register before work

Advice

Common problems we fix in Duns Tew

The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.

Clients typically get in touch after noticing one or more of the following:

  • Weathered joints at frame-to-structure perimeters
  • Patch repairs that keep failing
  • Perimeter sealant that has split or peeled away
  • Air leaks through failed facade joints

New units and refits on sites such as Hatch End Old Industrial Estate (1.6 miles south-east of Duns Tew) need their panel and perimeter joints sealed to the specification.

What your quote should include

  • The named product and why it was chosen
  • How they’ll work around occupants
  • Their pre-qualification and accreditations
  • Will CSCS-carded applicators be on site?

Our contractor checklist

Honest limits

Being straight saves everyone time. New sealant won’t cure:

  • Arranging specialist high-level access, which is planned with the client
  • Joints too narrow for the movement they take, which need redesign
  • Cracked or spalling substrates that need repair before sealing

If in doubt, call the office on 01277 525 020 or email us and we’ll say what we think before you book.

Facade sealing around Duns Tew: what changes locally

The South East is one of the drier parts of the UK. 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. At about 62 miles from central London, Duns Tew is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, which keeps mastic packages in demand.

Sites around Duns Tew get mastic sealed to the drawings and the programme, nothing improvised.
