Facade sealing in Townsend

Managing agents and owners in Townsend ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. If you have weathered joints at frame-to-structure perimeters and cold air coming in at window perimeters, we can help. Whether you call it commercial sealant work, mastic application or joint sealing, in Townsend it comes down to the same thing: the right product in a properly prepared joint.

In the countryside around places like Townsend, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is typically what’s needed.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Different surfaces, different methods

Render and coated surfaces

Rendered and painted facades need a sound edge for the sealant to bond to. Loose coatings are cleaned back first.

Cladding panel joints

On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself usually taking a day or two for a few elevations, and longer where access has to be moved around the building. For work around Townsend, we aim to finish in one visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  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. We walk the finished joints with you before handing over.

What we need from you

  • Tell us which areas need to stay in use
  • For older buildings, check the asbestos register before work
  • Move anything stored against the joints

Mastic packages on Townsend sites

Townsend is about 49 miles from central London. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme. Townsend is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, which is why external dates are agreed with the site manager.

On a healthcare site such as Park Prewett Hospital, 4.5 miles south-east of Townsend, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Units on estates such as Scion Business Park (to the north of Townsend) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

Townsend is about 3 miles south-west of Tadley, in Hampshire. We cover Townsend, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. Townsend is one of 723 places we cover in Hampshire. Sites around Reading have their own page, roughly 13 miles from Townsend.

Postcode districts covered here: RG26. If your building is just outside Townsend, we cover Wolverton Common (1 mile north), Axmansford (2 miles north), West Heath (2 miles east), Ramsdell (2 miles south-east) and Baughurst (2 miles north-east). Bigger towns within reach include Basingstoke (6 miles south-east), Andover (15 miles south-west), Alton (15 miles south-east), Tadley (3 miles north-east), Hook (11 miles east) and Popley (5 miles south-east).

What we are called out for in Townsend

Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.

Most enquiries start with one or more of the following:

  • Weathered facade joints that have lost their grip
  • Failed sealant on precast panel joints
  • Sealant pulling away from frames or panels
  • Failed seals around shopfront and entrance frames

School extensions, at buildings such as The Hurst School, usually run to the summer holidays, mastic included.

Questions to ask before you book

  • How joint depth will be controlled
  • Are they CHAS accredited or on Constructionline?
  • Their public liability cover
  • How the existing material will be dealt with

How to choose a sealant contractor

Townsend: questions and answers

Is Townsend too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

Is Scion Business Park, near Townsend, within your area?

Yes, sites like Scion Business Park are within our area, along with the rest of Townsend. To start, just call 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Do you offer coloured sealant?

It depends on the product. Some ranges are wide, others limited, so the available colours are confirmed with the quote.

Can you fit around our working hours?

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

Can you work in cold or wet weather?

We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Looking after the joints

After handover, these steps help:

  • Avoid patch repairs on failed facade joints
  • Ask about asbestos in pre-2000 mastic
  • Share access with other external trades
  • Report water ingress at frames as soon as it shows

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

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

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • Travel to remote or island sites
  • Phasing around occupants
  • How much there is to seal
  • Removal of failed or old sealant

There’s no price list, since every building and every scope is different. 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:

  • Whether an asbestos survey exists
  • Your programme or deadline
  • The site address and postcode
  • Drawings or a marked-up plan, if available

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.
