Facade sealing in Bletchley

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Facade sealing in Bletchley

We seal window and door perimeters, cladding panel joints, external facade joints and perimeter joints where frames meet the structure. Coping and flashing joints are included where sealant is the specified fix. Site teams most often ask us about weathered joints at frame-to-structure perimeters and water coming in around window frames, across shopfront frames, stone and brick facade joints and window and door perimeters. Facilities teams, main contractors and managing agents in Bletchley tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Construction in a town such as Bletchley is often smaller schemes: a few new flats, a school extension, a refurbished unit. A mastic package on a smaller site still needs the same care at window perimeters and facade joints.

A 12-month guarantee applies to all our work. Should something we installed fail, call 01277 525 020 or use the quote form and we’ll come back to it.

Our process

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. Most work in Bletchley is one building at a time: a school, a unit, an office or a block. We start with your photos, drawings or a site visit, then send a fixed quote.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
  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. We walk the finished joints with you before handing over.

Getting the site ready

  • Point out parking and an unloading spot
  • Confirm the product named in the specification
  • Send your site hours and access windows

Different surfaces, different methods

Perimeter joints at frames and structure

These frame-to-structure joints take a lot of movement and weather. We cut them out, prepare both faces and reseal to the specification.

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone, and primers go on where specified.

What sets the cost

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Joint width, depth and condition
  • Distance, for remote addresses
  • Whether the work must be split into stages
  • The product specified

The specified product makes a difference, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • The product your specification calls for
  • Approximate linear metres or a joint schedule
  • Anything awkward about access or site hours
  • When you need the work done

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, call the office on 01277 525 020 or send photos by email.

Common questions from Bletchley clients

Do you cover business parks and estates near Bletchley, such as Mount Farm Industrial Estate?

Yes. Estates, retail parks and business parks around Bletchley, Mount Farm Industrial Estate among them, are all within reach. A few photographs and the unit address let us price the work.

Is a hospital such as Milton Keynes University Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Should we check old sealant for asbestos?

It’s worth checking in any building from before 2000. The dutyholder holds the asbestos register, so ask for it before we start. If asbestos is suspected, work stops until it is tested.

Do you offer coloured sealant?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Will you check whether the sealant is causing the leak?

Yes. We check the sealant joints and report what we find as part of pricing. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.

Can you just add new sealant on top?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. Nothing else gives a bond that lasts.

Mastic packages on Bletchley sites

At about 44 miles from central London, Bletchley is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Bletchley has several hotels close by, all within 2 miles. Hotel extensions and refits usually have to fit around bookings, so mastic dates are tight.

Work at a hotel such as The Swan Hotel (1.1 miles east of Bletchley) tends to be programmed around bookings, mastic included. On a healthcare site such as Milton Keynes University Hospital, which lies north of Bletchley, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Recladding or extending a unit at a site like Mount Farm Industrial Estate, 1.5 miles north-east of Bletchley, brings panel joints and frame perimeters into the programme.

Bletchley is about 3 miles south of Milton Keynes, in Milton Keynes. We send applicators to Bletchley for facade joints, handled exactly as we handle every other area. Bletchley is one of 62 places we cover in Milton Keynes for facade joints. We also cover Oxford, around 27 miles from Bletchley.

Work on facade joints is covered throughout MK3, MK2, MK1 and MK4, whatever the building. For a building on Stanier Square, Downing Close and Wilton Avenue or nearby, send details and we’ll quote for facade joints. Bletchley sits on or close to the A421 and A4146, which helps when planning parking and deliveries for the job. We also cover Bletchley and Fenny Stratford (1 mile east), Water Eaton (1 mile east), Fenny Stratford (1 mile east), Newton Leys (1 mile south) and Newton Longville (2 miles south-west). A short drive away, we cover Milton Keynes (3 miles north), Newport Pagnell (6 miles north), Whitehouse (4 miles north-west), Middleton (4 miles north-east), Olney (11 miles north) and Shenley Church End (3 miles north-west). Among the larger centres in Milton Keynes is Bletchley, and we take on facade joints for its commercial and public buildings.

When to bring in a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Keeping the joints sound

To get the most from the new sealant:

  • Brief window cleaners about newly sealed joints
  • Check that rainwater leaves the facade the way it was designed to
  • Insist on a full cut-out when joints are renewed
  • Plan facade sealing alongside redecoration

Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards using a matching sealant.

Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in.
