How we handle facade sealing in Twyford

Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure on offices, blocks and industrial units. Where sealant is the specified fix, we also take on coping and flashing joints. If you’re dealing with cold air coming in at window perimeters and sealant pulling away from frames or panels, we can help, whatever the surface. Most enquiries from Twyford start with one failed joint and grow into a wider look at the building: 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 Twyford bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Mastic packages on Twyford sites

Twyford is about 50 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, so mastic packages have to keep pace with busy programmes. Twyford is in the South East, one of the UK’s drier regions. 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.

With historic properties like Claydon House (to the east of Twyford) in the area, refurbishment work often meets old masonry that needs compatible sealants. School extensions, at buildings such as Twyford C of E School, usually run to the summer holidays, mastic included. When units on a site such as Three Bridge Mill Industrial Park, 0.7 miles to the north-east of Twyford, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Twyford is about 5 miles south-west of Buckingham, in Buckinghamshire. Twyford sits inside our coverage and the rest of Buckinghamshire, with the same fixed quotes and 12-month guarantee as everywhere else. Twyford is one of 308 places in Buckinghamshire on our list for facade joints. There’s a separate page for Oxford, roughly 15 miles from Twyford.

Business premises anywhere in MK18 are within our area for facade joints. We cover commercial and managed buildings on Mill Lane, Main Street and School Lane. If your building is just outside Twyford, we cover Poundon (1 mile south-west), Charndon (1 mile south), Calvert (2 miles south-east), Hillesden (2 miles north-east) and Preston Bissett (2 miles north).

When it isn’t the sealant

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Arranging specialist high-level access, which is planned with the client
  • Movement beyond what any sealant can handle
  • Cracked or spalling substrates that need repair before sealing

Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

Joints and surfaces we work on

Twyford: questions and answers

Is Twyford too small for you to travel to?

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.

Is Three Bridge Mill Industrial Park, near Twyford, within your area?

Yes. Estates, retail parks and business parks around Twyford, Three Bridge Mill Industrial Park among them, are all within reach. To start, just call the office on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

How long does a job like this take?

That varies with the scale of the job, 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’ll give you a timescale with the quote.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

Do you guarantee your work?

Yes. Workmanship is guaranteed for 12 months on every job.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Maintenance after handover

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep the sealant details on the building file
  • Investigate damp beside windows promptly
  • Ask about asbestos in pre-2000 mastic
  • Insist on a full cut-out when joints are renewed

Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration.

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.

Why deal with it now?

Patch repairs over old sealant tend to come back. A full cut-out and fresh bead is the repair that holds, so you aren’t paying for the same joint twice. Converted and older buildings near places like Twyford tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Pricing facade joints depends on how many there are, their condition and the access, plus any specification you are working to. Call for a quote.

Why us?

  • Public liability insurance in place
  • Joints cleaned back to sound surfaces
  • Clear, fixed quotes
  • Colour agreed before work starts

Cost factors for facade joints

Before we quote, we look at:

  • Induction, permit and paperwork requirements
  • Removal of failed or old sealant
  • Location, for remote and island sites
  • Access and working height

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

What to include in your enquiry

To price the job accurately, we need to understand the site. Send us:

  • How the joints are reached, and at what height
  • Drawings or a marked-up plan, if available
  • The asbestos register, for older buildings
  • Specification clauses that apply

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or email the details over.

Owners, agents and contractors

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, and each stage is agreed with your contact.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. For a building around Twyford, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We start with photos, drawings or a visit to see the joints and agree access.
  2. We confirm the joint type, movement and the specified product.
  3. The existing bead comes out in full and both faces cleaned back.
  4. Primer is applied where the maker specifies it.
  5. Backing rod is fitted and the new sealant gunned in and tooled.
  6. We go over the completed work with you before leaving.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Send asbestos survey details if the building is pre-2000
  • Clear stock, furniture or equipment away from the joints
