Facade sealing near Mill Green

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What happens if it’s left?

Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. Around Mill Green, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.

The product called for affects the cost, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What you get with us

  • CHAS accredited
  • A range of standard colours, depending on the product
  • Colour options checked against the specified product
  • 12 months’ guarantee on every job

About our facade sealing in Mill Green

External joints face UV, rain, temperature swings and building movement all year. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. We work on cladding panel joints, perimeter joints where frames meet the structure and window and door perimeters, and what we are called in for most is patch repairs that keep failing and old perimeter mastic that has dried out. A single leaking joint is often how a building in Mill Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Conversions of older rural buildings near smaller places such as Mill Green bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Work we carry out in Hampshire comes with a 12-month guarantee. Should something we installed fail, phone 01277 525 020 or send details through our quote form and we will come back to it.

Building and refurbishing in Mill Green

The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager. At about 50 miles from central London, Mill Green 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 refurbishing units at places like New Greenham Business Park, 1.9 miles to the north-west of Mill Green, the mastic covers cladding panels, roller-door and window perimeters. For a contractor working at a hospital such as West Berkshire Community Hospital (3.6 miles north-west of Mill Green), perimeter and facade sealing is planned around patients and deliveries. Historic houses such as Shaw House (4.6 miles north-west of Mill Green) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Mill Green is about 3 miles south of Thatcham, in Hampshire. Any commercial site in Mill Green is covered, for single jobs and planned programmes alike. 723 places across Hampshire fall within our area, Mill Green among them. Our Reading page has more on work in that area (13 miles or so).

From enquiry to sign-off

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Rural sites near Mill Green may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. Access, site rules and timing are settled with the client up front.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  5. Sealant is gunned in and tooled hard onto both faces.
  6. Once signed off, the work carries our 12-month guarantee.

Questions we are asked in Mill Green

Is Mill Green off your patch?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Does your area include sites such as New Greenham Business Park, near Mill Green?

Yes, sites like New Greenham Business Park are within our area, along with the rest of Mill Green. To start, just give us a call on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

What’s the quickest route to a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Can you fit around our working hours?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Will you check whether the sealant is causing the leak?

Yes. We look at the perimeter sealant and tell you whether it has failed before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Providing access systems for the work
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Joints whose design needs changing by the specifier

Not sure which it is? You can call the office on 01277 525 020 or send photos by email and we’ll tell you honestly before you book.

Joints and surfaces we work on

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

Looking after the joints

Problems stay small when the joints are checked regularly. In particular:

  • Report water ingress at frames as soon as it shows
  • Walk the elevations once or twice a year
  • Brief window cleaners about newly sealed joints
  • Keep the sealant details on the building file

Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.

In pre-2000 buildings, check the asbestos register before old sealant is cut out. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.
