Facade sealing for Shalstone sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

On site: what to expect

Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. For a building around Shalstone, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. Each joint is cut out and the edges inspected.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Getting the site ready

  • Let us know about inductions and permits
  • Arrange parking or a loading space
  • Have the specification and drawings to hand

Facade sealing in Shalstone, done properly

Managing agents and owners in Shalstone ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. Each job carries our 12-month guarantee. We work on coping and flashing joints, window and door perimeters and perimeter joints where frames meet the structure, and the failures we’re asked to look at most are discoloured or dirty facade joints and cold air coming in at window perimeters. Whoever orders the work in Shalstone, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Around smaller places like Shalstone, building work usually 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.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Common problems we fix in Shalstone

When sealant lets go of a frame or panel, the cause is often the preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and movement soon pulls it away.

Any of the following is a good reason to get the joints checked over:

  • Previous reseals run over old sealant
  • Water coming in around window frames
  • Failed seals around shopfront and entrance frames
  • Staining on stone next to old sealant

Historic houses such as Stowe House (to the east of Shalstone) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Questions to ask before you book

  • How joint depth will be controlled
  • Proof of insurance
  • Whether their applicators hold CSCS cards
  • How they’ll work around occupants

Contractors’ notes for Shalstone

Shalstone 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. At about 55 miles from central London, Shalstone is within reach of the capital. 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.

Building work at universities like University of Buckingham (4.2 miles south-east of Shalstone) is often timed for the summer, mastic included. On a healthcare site such as Brackley Community Hospital, which lies west of Shalstone, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.

Shalstone is in Buckinghamshire. We cover commercial sites throughout Shalstone, for single jobs and planned programmes alike. We work across 308 places in Buckinghamshire, large and small. We also cover Oxford, some 20 miles away.

FAQs: Shalstone

Can you take on a job at a hospital such as Brackley Community Hospital?

Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.

Is Shalstone off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work on upper floors?

Access is planned with you before we quote. Let us know what access is in place or planned.

Will rain stop the work?

Year-round work is possible as long as joints are dry and temperatures suit the product. Frost and condensation on glass and steel are common on winter mornings, and we build that into the programme.

Do you install glazing systems?

No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, such as perimeter joints where frames meet the structure.

Can you find out why a window is leaking?

Yes. We check the sealant joints and report what we find. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Is your workmanship covered by a guarantee?

Yes. Our workmanship is backed for 12 months.

What the job involves on each surface

Cladding panel joints

Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface.

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint, not the framing or glazing itself.

Honest limits

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Water getting in through cracked render or porous masonry
  • Movement beyond what any sealant can handle
  • Replacing glass or failed glazing units

If you’re not sure, just phone 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Surfaces we seal

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

What sets the cost

Each job is priced on its own details. The things that drive the figure:

  • Which sealant the job calls for
  • Location, for remote and island sites
  • Induction, permit and paperwork requirements
  • Any access equipment needed

Access can matter as much as the joints themselves: 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.

Sending details for a quote

Whether it’s one area or a whole building, the same details help:

  • Whether an asbestos survey exists
  • A wide shot and a close-up of the area
  • The type of building and who uses it
  • The postcode of the building

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or give us a call on 01277 525 020 or email a schedule or drawings to discuss it first.
