Facade sealing across Saunderton

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Building owners, agents and FMs in Saunderton

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

How we handle facade sealing in Saunderton

A good facade joint depends on design as much as product. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. If you’re dealing with staining on stone next to old sealant and sealant pulling away from frames or panels, we can put it right. One point of contact handles commercial sealant work in Saunderton from the first photos to the final walk-round, whether it’s one building or several.

Sites around smaller places like Saunderton can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photos and the programme and we will quote to suit.

A 12-month guarantee applies to all our work in Buckinghamshire. Should something we installed fail, call the office on 01277 525 020 or send details through our quote form and we will come back to it.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Saunderton are usually planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  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. We remove the old bead and check the edges are sound.
  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.

Advice

General trades versus a specialist

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Mastic packages on Saunderton sites

Saunderton is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack. Central London is about 34 miles from Saunderton. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.

University estates such as Buckinghamshire New University (Wycombe Campus), 4.5 miles south-east of Saunderton, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal. School extensions, at buildings such as Bledlow Ridge School, normally run to the summer holidays, mastic included. Units on estates such as Crownfield Industrial Estate, 0.8 miles to the north of Saunderton, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Saunderton is about 5 miles north-west of High Wycombe, in Buckinghamshire.

What sealant work can’t fix

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Cracked or spalling substrates that need repair before sealing
  • Joints too narrow for the movement they take, which need redesign
  • Replacing glass or failed glazing units

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

Surfaces we seal

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

Different surfaces, different methods

Perimeter joints at frames and structure

The joint around a framed system, where it meets the structure, needs sealant. We seal those perimeter joints.

Coping and flashing joints

Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building.

Common questions from Saunderton clients

Can you work on a hospital site such as Wycombe Hospital?

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

Do you cover business parks and estates near Saunderton, such as Crownfield Industrial Estate?

Yes, sites like Crownfield Industrial Estate are within our area, along with the rest of Saunderton. Send details of the unit and the work through our quote form for a quick quote.

What site paperwork can you supply?

Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.

Is colour matching possible?

It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a quote and we will price it properly.

Can you find out why a window is leaking?

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

Do you guarantee your work?

Yes. Our workmanship is backed for 12 months.

Leave it or put it right?

Failed joints let in more than water: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. Around Saunderton, it’s better to renew all the failing joints at once. Send photos of each area and we will quote for the lot.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
