Facade sealing for businesses in Winslow

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

When to bring in a specialist

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

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.

How we handle facade sealing in Winslow

Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. The enquiries we see most involve patch repairs that keep failing and facade joints cracked through the middle, across coping and flashing joints, shopfront frames and window and door perimeters. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Winslow, preparation and product choice get the time they need.

Conversions around smaller places like Winslow often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently, in a colour the planners or architect are happy with.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Winslow: questions and answers

Will you take on work at estates like Station Road Industrial Estate, close to Winslow?

Yes, sites like Station Road Industrial Estate are within our area, along with the rest of Winslow. To start, just speak to us on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Is a smaller place like Winslow outside your area?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we’ll confirm them with the quote.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.

Can staff carry on working while you are here?

Normally, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Can you fit around our working hours?

Mention the site’s hours and access windows in your enquiry, and we’ll schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Aftercare for building managers

Once the work is signed off, a little attention goes a long way:

  • Report water ingress at frames as soon as it shows
  • Plan facade sealing alongside redecoration
  • Record the product and colour used on each elevation
  • Ask about asbestos in pre-2000 mastic

Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.

Use each reseal to correct the joint: correct depth, proper backing and a sealant that can take the movement. A well-designed joint lasts longer than a like-for-like copy of a failed one.

Building and refurbishing in Winslow

Winslow is about 46 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand. Rainfall across the South East, Winslow included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack.

For contractors refurbishing units at places like Station Road Industrial Estate, less than half a mile to the north-east of Winslow, the mastic covers cladding panels, roller-door and window perimeters. For contractors at a school such as Sir Thomas Fremantle School, sealing has to be finished before term starts. For a contractor at a hotel such as The Bell Hotel (under half a mile south of Winslow), the mastic often has to be finished before a reopening date.

Winslow is about 6 miles south-east of Buckingham, in Buckinghamshire. Winslow sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Across Buckinghamshire, 308 places are covered, including Winslow. Oxford is covered too, around 20 miles from Winslow.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself usually takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. Several jobs near Winslow can be grouped on one trip. Mention the building’s opening times and we’ll work within them.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Before we start on site

  • Confirm the product named in the specification
  • Point out any areas we must not close
  • Let building users know which areas are affected

Getting a fixed quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Honest limits

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Installing or repairing glazing systems
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Movement beyond what any sealant can handle

If in doubt, call 01277 525 020 or send photos by email and we will say what we think.

Where we work in Winslow

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

Why it’s worth doing now in Winslow

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. For buildings in places like Winslow, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Why appoint us

  • One phone line for London, the South East and Scotland
  • Colour options checked against the specified product
  • Clear, fixed quotes
  • 12-month guarantee on workmanship
