When to call us in Childrey
Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.
Clients typically get in touch after noticing something like this:
- Damp patches beside frames after rain
- Weathered facade joints that have lost their grip
- Failed sealant on precast panel joints
- Sealant pulling away from frames or panels
When a school such as The Ridgeway Church of England (C) Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.
Questions to ask before you book
- Will RAMS and insurance details be available?
- The named product and why it was chosen
- Do they follow the manufacturer’s priming guidance?
- Whether old or failed sealant will be cut out, not overlaid
Facade sealing in Childrey, done properly
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on perimeter joints where frames meet the structure, stone and brick facade joints and coping and flashing joints, and the failures we are asked to look at most are air leaks through failed facade joints and patch repairs that keep failing.

Construction in and around smaller places such as Childrey 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.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

- Movement beyond what any sealant can handle
- Cracked or spalling substrates that need repair before sealing
If in doubt, ring 01277 525 020 or email the details over and we will say what we think before you book.

Common questions from Childrey clients
Will you take on work at estates like W&G Industrial Estate, close to Childrey?
Yes, sites like W&G Industrial Estate are within our area, along with the rest of Childrey. A few photographs and the unit address let us price the work.
Is Childrey off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
How do we ask for a quote?
The quote form is the simplest route, though you can also give us a call on 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
Do you install glazing systems?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.
Who decides which product is used?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
What type of sealant goes on window perimeters?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, as the specification or substrate requires.
Diagnose, treat, sign off
A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. For a building around Childrey, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Getting the site ready
- Share the asbestos register for older buildings
- Tell us what induction or permit system the site runs
- Arrange parking or a loading space
Request 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 photos and a few notes.
Advice
Surface by surface
Brick and stone facades
Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported first.
Mastic packages on Childrey sites
Central London is about 60 miles from Childrey. Towns within reach of London tend to keep building, from flats to offices and schools, and main contractors there need mastic that keeps to the programme. Childrey sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager.
New units and refits on sites such as W&G Industrial Estate, 1.1 miles to the north-east of Childrey, need their panel and perimeter joints sealed to the specification. For a contractor working at a hospital such as Wantage Community Hospital, 2.6 miles to the east of Childrey, perimeter and facade sealing is planned around patients and deliveries.
Childrey is about 2 miles west of Wantage, in Oxfordshire. Any commercial site in Childrey is covered, for single jobs and planned programmes alike. We work across 423 places in Oxfordshire. Sites around Oxford have their own page, about 16 miles away.
Postcode districts covered here: OX12. If your site is on High Street, Hollow Way and Stowhill or close by, send details and we will quote for facade joints. Nearby places we also cover include West Challow (1 mile north-east), East Challow (1 mile east), Letcombe Regis (1 mile south-east), Letcombe Bassett (2 miles south-east) and Wantage (2 miles east). A short drive away, we cover Didcot (10 miles east), Abingdon-on-Thames (11 miles north-east), Witney (14 miles north), Carterton (14 miles north), Grove (3 miles north-east) and Faringdon (7 miles north-west).

Why it’s worth doing now in Childrey
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Water through a failed joint rarely stays where it starts, often turning up far from the joint. Halls, stores and units around places like Childrey may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
