Mastic packages on Sonning Common sites

Rainfall across the South East, Sonning Common included, is lower than in many parts of the UK. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager. At about 38 miles from central London, Sonning Common is within reach of the capital. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes.

For contractors at a school such as Sonning Common Primary School, sealing has to be finished before term starts. Historic houses such as Greys Court, 2.2 miles north-east of Sonning Common, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Facade sealing for commercial buildings in Sonning Common

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters. If you’re dealing with old perimeter mastic that has dried out and cold air coming in at window perimeters, we can put it right, on stone and brick facade joints, perimeter joints where frames meet the structure and shopfront frames alike. A single leaking joint is often how a building in Sonning Common first comes to us: we look at the rest while we are there and tell you what we find.

Around places like Sonning Common, a lot of construction is the conversion of older buildings, and the sealant at those junctions has to cope with two materials that move differently.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

What happens if it’s left?

Failed joints let in more than water: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Over time, UV, weather and movement wear any sealant out. Replacing it before it fails keeps water out.

Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

From enquiry to sign-off

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. For a job in Sonning Common, the main thing is a clear picture of the work. A fixed quote follows.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  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. The completed runs are checked with you, then the 12-month guarantee applies.

Before we start on site

  • Point out parking and an unloading spot
  • Flag any permit to work we’ll need
  • Let building users know which areas are affected

Advice

Owners, agents and contractors

Building owners and managing agents use us on everything from one building to a spread of sites around Sonning Common. Several sites can go on one quote, so there’s one set of paperwork to deal with.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Common problems we fix in Sonning Common

Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint, then it splits or peels.

Most enquiries start with one or more of the following:

  • Gaps between rainscreen or cladding panels
  • Unsightly perimeter sealant on a visible elevation
  • Cold air coming in at window perimeters
  • Weathered facade joints that have lost their grip

On a campus such as University of Reading, 3.2 miles south-east of Sonning Common, new teaching buildings and residences are usually built and refurbished around the academic year.

Questions to ask before you book

  • Their plan for phasing and protecting the area
  • How joint depth will be controlled
  • Is the sealant right for the movement and the substrate?
  • Will RAMS and insurance details be available?

Questions to ask before you appoint anyone

Questions we’re asked in Sonning Common

Will you plan work around the academic year at somewhere like University of Reading?

Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is Sonning Common too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Will you just go over the old sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

How much does the work cost?

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

Do you take on multi-site work?

Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.

Can you work on upper floors?

That varies with the building and the access on offer. Share what access exists or is planned when you send details.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators, which many sites require.

Quoting for work in Sonning Common

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

  • How much existing material needs removing
  • Site requirements such as inductions and permits
  • Backing rod, priming and other preparation
  • How much there is to seal

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Details that help us quote

There’s no need for a formal survey. A few details are enough to get going:

  • Access details, including height
  • The asbestos register, for older buildings
  • The type of building and who uses it
  • Drawings or a marked-up plan, if available

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or email the details over.

After the work

For the best life from the joints:

  • Walk the elevations once or twice a year
  • Never let anyone seal over old sealant
  • Note when each elevation was last resealed
  • Ask about asbestos in pre-2000 mastic

Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant.

Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money.
