Maintenance after handover

For the best life from the joints:

  • Report water ingress at frames as soon as it shows
  • Keep sills, gutters and drainage paths clear
  • Walk the elevations once or twice a year
  • Avoid harsh cleaners on facade sealant

Keep a note of which product went in and when. It helps when matching repairs or planning the next reseal.

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

Facade sealing in Nuneham Courtenay, done properly

Managing agents and owners in Nuneham Courtenay ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. We work on perimeter joints where frames meet the structure, window and door perimeters and cladding panel joints, and the usual reasons a site gets in touch are failed sealant on precast panel joints and air leaks through failed facade joints. A single leaking joint is often how a building in Nuneham Courtenay first comes to us: we look at the rest while we’re there and tell you what we find.

Around smaller places like Nuneham Courtenay, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be one of these:

  • Cracked or spalling substrates that need repair before sealing
  • Joints whose design needs changing by the specifier
  • Specialist high-level access methods

Not sure which it is? You can call 01277 525 020 or send details through our quote form and we’ll tell you honestly.

Joints and surfaces we work on

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

Our process

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you. For a building around Nuneham Courtenay, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. First we review photographs, drawings or what we saw on a visit, and agree how each joint will be reached.
  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.

What we need from you

  • Send your site hours and access windows
  • Let building users know which areas are affected
  • Explain the parking and delivery arrangements

Advice

Nuneham Courtenay: questions and answers

Do you take on work at healthcare sites like Littlemore Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will you plan work around the academic year at somewhere like Oxford Brookes University?

Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.

Do you replace failed glazing units?

No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters on commercial buildings.

Does the weather affect the work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

How do we ask for a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.

What the job involves on each surface

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed with a product suited to glazing perimeters.

Cladding panel joints

On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them to the correct depth.

Work for main contractors and building owners

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, with each stage agreed with your site contact.

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Facade sealing around Nuneham Courtenay: what changes locally

Nuneham Courtenay lies roughly 49 miles out from central London. 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. Nuneham Courtenay is in the South East, one of the UK’s drier regions. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.

School extensions, at buildings such as Marsh Baldon Church of England Controlled School, usually run to the summer holidays, mastic included. Historic houses such as Clifton Hampden Manor (2.3 miles south of Nuneham Courtenay) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. When units on a site such as Sandford Lane Industrial Estate (to the north-west of Nuneham Courtenay) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
