Facade sealing for Tetsworth sites

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

When something else is needed

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

  • Damp caused by condensation inside the building
  • Providing access systems for the work
  • Damaged frames that need replacing

If in doubt, ring 01277 525 020 or email the details over and we’ll say what we think.

What we seal

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

Facade sealing in Tetsworth, done properly

External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. We work on shopfront frames, perimeter joints where frames meet the structure and coping and flashing joints, and the failures we’re asked to look at most are perimeter sealant that has split or peeled away and weathered joints at frame-to-structure perimeters. A single leaking joint is often how a building in Tetsworth first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Sites around smaller places like Tetsworth can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photos and the programme let us give a fixed quote.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

What affects the price in Tetsworth

To price the job, we consider:

  • Quantities, in metres or numbers
  • Induction, permit and paperwork requirements
  • Travel to remote or island sites
  • Joint width, depth and condition

There’s no price list, because the scope varies so much from one building to the next. Call for a quote.

Details that help us quote

However big the job, the same details help:

  • The asbestos register, for older buildings
  • The type of building and who uses it
  • Anything awkward about access or site hours
  • When you need the work done

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, speak to us on 01277 525 020 or send details through our quote form.

Facade sealing around Tetsworth: how the place shapes the job

Tetsworth lies roughly 42 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, which keeps mastic packages in demand. Tetsworth sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.

On a healthcare site such as Thame Community Hospital, 2.8 miles to the north-east of Tetsworth, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. When units on a site such as Christmas Hill Business Park (to the north of Tetsworth) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package. When a school such as Tetsworth Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Tetsworth is about 3 miles south-west of Thame, in Oxfordshire. We send applicators to Tetsworth for facade joints, handled exactly as we handle every other area. Our Oxfordshire coverage takes in 423 places, from busy centres to rural villages. Our Oxford page has more on work in that area, about 10 miles away.

How a job runs

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. For work around Tetsworth, we aim to finish in one visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. Photos, drawings or a visit tell us about the joints and the access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full.
  4. Primer goes on where the product data asks for it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Preparing the site

  • Send your site hours and access windows
  • Make sure the joints can be reached
  • For older buildings, check the asbestos register before work

Advice

Owners, agents and contractors

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.

Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

Your questions answered

Will you take on work at estates like Christmas Hill Business Park, close to Tetsworth?

Yes. Estates, retail parks and business parks around Tetsworth, Christmas Hill Business Park among them, are all within reach. To start, just give us a call on 01277 525 020 or email us with the unit, the joints involved and your access times.

Is hospital work, at somewhere like Thame Community Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Do you offer coloured sealant?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Do you replace failed glazing units?

No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.

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, so ask for it before we start. If asbestos is suspected, work stops until it is tested.

Leave it or put it right?

Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. Converted and older buildings near places like Tetsworth tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What the job involves on each surface

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. The rod limits depth, leaving the bead able to flex.

Coping and flashing joints

Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.
