Facade sealing in Aspley Heath

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

Looking after the joints

A few simple habits keep the new joints working:

  • Check that rainwater leaves the facade the way it was designed to
  • Combine resealing with other works that need access
  • Investigate damp beside windows promptly
  • Add perimeter sealant to planned maintenance checks

Record the sealant type and date on the building file. Future work can then match the product and colour across the elevation.

Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.

About our facade sealing in Aspley Heath

External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. We work on coping and flashing joints, stone and brick facade joints and cladding panel joints, and the failures we are asked to look at most are staining on stone next to old sealant and failed seals around shopfront and entrance frames. A single leaking joint is often how a building in Aspley Heath first comes to us: we look at the rest while we are there and tell you what we find.

For a site near Aspley Heath, the mastic visit is planned so the right sealants, primers and backing rod are on hand, timed to the stage the job has reached. Drawings, photographs and the programme let us give a fixed quote.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

How the quote is worked out

Before we quote, we look at:

  • Site requirements such as inductions and permits
  • Location, for remote and island sites
  • How accessible the joints are
  • Whether the work must be split into stages

Pricing facade joints depends on quantities, condition and access. Call for a quote.

Details that help us quote

A good diagnosis starts with the right details. Let us know:

  • What the building is and how it’s used
  • Asbestos survey details if the building is older
  • Where the site is, with the postcode
  • How the joints are reached, and at what height

To get a fixed quote, call 01277 525 020 or email drawings and photos. You can also send details through our quote form.

Common questions from Aspley Heath clients

Can you take on a job at a hospital such as Milton Keynes University Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Is Aspley Heath too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you check whether the sealant is causing the leak?

Yes. Photos are often enough to start, followed by a visit if needed. Many frame leaks are sealant failures, though not all, and we will be honest about which it is.

What’s the quickest route to a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or send details through our quote form. Include photographs or drawings if you have them.

Do you provide access for facade work?

We agree access with the client at the start. Tell us about access: existing scaffold, what you are arranging and any site restrictions.

How long does a typical visit take?

It depends on the scope, but the work normally takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

What sealant work can’t fix

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Replacing glass or failed glazing units
  • Arranging specialist high-level access, which is planned with the client
  • Joints too narrow for the movement they take, which need redesign

Not sure which it is? You can ring 01277 525 020 or email the details over and we’ll tell you honestly.

Surfaces we seal

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

When to bring in a specialist

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

When to call us in Aspley Heath

Overlaying old sealant is a common shortcut that fails quickly. Cured silicone won’t accept a new silicone bead, and the patch soon lifts.

Most enquiries start with one or more of the following:

  • Perimeter joints where frames meet the structure
  • Cladding panel joints that have opened up
  • Patch repairs that keep failing
  • Damp patches beside frames after rain

For contractors on a campus like The Open University (2.8 miles north-west of Aspley Heath), facade and perimeter sealing has to fit around students and term dates.

What to look for in a quote

  • The terms of the workmanship guarantee
  • Who will actually carry out the work
  • Is the sealant right for the movement and the substrate?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Choosing a commercial sealant contractor

Mastic packages on Aspley Heath sites

Plenty of hotels sit less than 2 miles from Aspley Heath. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight. At about 42 miles from central London, Aspley Heath is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme.

On a healthcare site such as Milton Keynes University Hospital (3.9 miles west of Aspley Heath), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Hotel extensions and refits, at places such as Greens Hotel, which lies north of Aspley Heath, typically run between busy periods, so the sealing is squeezed into short windows.
