Facade sealing in Shotover Hill, done properly

We don’t install glazing systems or replace glass. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. We work on window and door perimeters, shopfront frames and coping and flashing joints, and what we are called in for most is cladding panel joints that have opened up and hard, chalky sealant that no longer flexes. Most enquiries from Shotover Hill start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

On a small site around Shotover Hill, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.

Every job is signed off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

What affects the price in Shotover Hill

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Whether old sealant has to be cut out first
  • Quantities, in metres or numbers
  • Access and working height
  • Location, for remote and island sites

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Sending details for a quote

Good information means a firmer quote. When you get in touch, include:

  • The site address and postcode
  • Specification clauses that apply
  • Any dates the work must fit around
  • Photos of the joints, close up and from further back

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. If you have questions first, give us a call on 01277 525 020 or email a schedule or drawings.

Owners, agents and contractors

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Facade sealing in Shotover Hill: the local picture

Central London is about 50 miles from Shotover Hill. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and each scheme needs its mastic sealed to programme. Shotover Hill sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.

For contractors on a campus like Oxford Brookes University, 1.3 miles to the west of Shotover Hill, facade and perimeter sealing has to fit around students and term dates. On a healthcare site such as Churchill Hospital, which lies west of Shotover Hill, 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 Shotover Trading Estate, under half a mile north of Shotover Hill, brings panel joints and frame perimeters into the programme.

Why deal with it now?

The longer a failed joint is left, the more the substrate suffers: wet edges break down, so repairs may be needed before resealing. Acting at the first sign of splitting keeps the fix simple. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. For a job in Shotover Hill, the main thing is a clear picture of the work. You will then get a fixed price for the work.

  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. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Flag any permit to work we’ll need
  • Share the asbestos register for older buildings
  • Make sure the joints can be reached

Questions we are asked in Shotover Hill

Will you plan work around the academic year at somewhere like Oxford Brookes University?

Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Is Shotover Hill too far out for you?

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

Do we need an asbestos check before resealing?

For older buildings, yes, check before work starts. The duty to manage asbestos sits with the dutyholder. Suspect material is left alone until it has been tested.

How do we ask for a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email a schedule or drawings. Include photographs or drawings if you have them.

Is it okay to overlay old mastic?

No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the joint cleaned back to sound material. Nothing else gives a bond that lasts.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Is it fine to apply new sealant on top of old?

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

Aftercare for building managers

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

  • Plan facade sealing alongside redecoration
  • Walk the elevations once or twice a year
  • Check the asbestos register before old mastic is disturbed
  • Check that rainwater leaves the facade the way it was designed to

Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade instead of soaking the joints.

Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones.

What sealant work can’t fix

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Arranging specialist high-level access, which is planned with the client
  • Water getting in through cracked render or porous masonry
  • Joints too narrow for the movement they take, which need redesign

If you’re not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.
