Facade sealing in Crowmarsh Gifford, done properly

Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. We work on cladding panel joints, stone and brick facade joints and perimeter joints where frames meet the structure, and what we’re called in for most is hard, chalky sealant that no longer flexes and cladding panel joints that have opened up. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Crowmarsh Gifford it comes down to the same thing: the right product in a properly prepared joint.

Construction in and around smaller places such as Crowmarsh Gifford 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.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Mastic packages on Crowmarsh Gifford sites

Crowmarsh Gifford is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so we time external mastic for dry faces and agree it with the site team. A number of hotels sit less than 2 miles from Crowmarsh Gifford. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

Older buildings in the area around Crowmarsh Gifford, such as Brightwell Manor (2.7 miles west of Crowmarsh Gifford), need care when sealed: the product has to suit soft or historic materials. When a school such as Crowmarsh Gifford Church of England School is extended or refurbished, the mastic package is often squeezed into the holidays.

Aftercare for building managers

Problems stay small when the joints are checked regularly. In particular:

  • Add perimeter sealant to planned maintenance checks
  • Check the asbestos register before old mastic is disturbed
  • Never let anyone seal over old sealant
  • Brief window cleaners about newly sealed joints

If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

For managing agents and facilities managers

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Questions we’re asked in Crowmarsh Gifford

Is a smaller place like Crowmarsh Gifford outside your area?

No. Places such as Crowmarsh Gifford are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Does your area include sites such as Hithercroft Industrial Estate, near Crowmarsh Gifford?

Yes. Estates, retail parks and business parks around Crowmarsh Gifford, Hithercroft Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Do you replace failed glazing units?

No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters across the facade.

Do we need an asbestos check before resealing?

It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder. If asbestos is suspected, work stops until it is tested.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Common problems we fix in Crowmarsh Gifford

Sun, rain and temperature swings wear facade sealant down over the years. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.

It’s worth sending us details if you spot any of the following:

  • Cladding panel joints that have opened up
  • Cold air coming in at window perimeters
  • Discoloured or dirty facade joints
  • Leaks at window and door perimeters

New wings at hospitals like Wallingford Community Hospital (to the west of Crowmarsh Gifford) bring long runs of window and panel joints to seal.

Comparing quotes

  • Will RAMS and insurance details be available?
  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Their plan for phasing and protecting the area

Questions to ask before you appoint anyone

Different surfaces, different methods

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. Rod placed at the right depth lets the bead stretch.

Render and coated surfaces

Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.

Why it’s worth doing now in Crowmarsh Gifford

A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure. One visit to deal with every failing joint makes more sense than several trips to a place like Crowmarsh Gifford, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Why appoint us

  • Colour options checked against the specified product
  • Clear, fixed quotes
  • Failed material removed, not covered up
  • One phone line for London, the South East and Scotland

How a job runs

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and we clear our waste as we work. Rural sites near Crowmarsh Gifford may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with photographs, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. Failed beads are removed in full and both faces cleaned back.
  4. Primer is applied where the maker specifies 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 any specification or drawings in advance
  • Send asbestos survey details if the building is pre-2000
  • Share your working hours and any access restrictions
