Need facade sealing in Thames Ditton?

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

When it isn’t the sealant

Being straight saves everyone time. Fresh joints won’t solve:

  • Movement beyond what any sealant can handle
  • Leaks from roofs, gutters or failed flashings rather than sealant joints
  • Work on the window or framing system itself

If you’re not sure, just ring 01277 525 020 or email the details over and we will give you a straight answer.

What we seal

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

About our facade sealing in Thames Ditton

A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, while rod fixes the depth and stops the bead sticking to the rear, often at around 2:1 width to depth, as the manufacturer advises. The enquiries we see most involve sealant pulling away from frames or panels and patch repairs that keep failing, on coping and flashing joints, perimeter joints where frames meet the structure and cladding panel joints. One point of contact handles commercial sealant work in Thames Ditton from the first photos to the final walk-round, whether it’s one building or several.

On a small site around Thames Ditton, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we’ll time the work so nothing waits on us.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Different surfaces, different methods

Brick and stone facades

Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one, and mask the edges carefully.

Perimeter joints at frames and structure

Where framed systems such as shopfronts meet the building structure, there is a perimeter joint to seal. Our work is that perimeter joint.

What affects the price in Thames Ditton

Your fixed quote is built from the real scope. It takes account of:

  • Phasing around occupants
  • Quantities, in metres or numbers
  • Backing rod, priming and other preparation
  • The site’s rules and procedures

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Details that help us quote

However big the job, the same details help:

  • Where the site is, with the postcode
  • Any dates the work must fit around
  • The product your specification calls for
  • Clear photographs of the problem areas

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Thames Ditton: questions and answers

Does your area include sites such as Fairfield Trade Park, near Thames Ditton?

Yes. Estates, retail parks and business parks around Thames Ditton, Fairfield Trade Park among them, are all within reach. Photos and a short description are enough for a first look.

Do you take on work at healthcare sites like Molesey Community Hospital?

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

What site paperwork can you supply?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Can you handle several sites?

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

What hours do you work?

We are 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.

Does weather matter for sealant work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Share access with other external trades
  • Check the asbestos register before old mastic is disturbed
  • Insist on a full cut-out when joints are renewed
  • Record the product and colour used on each elevation

Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal without guesswork.

Coordinate facade sealing with other external works. One set-up for several trades saves money and limits disruption.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. What matters most for a job in Thames Ditton is a clear list of what needs doing. A fixed quote follows.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  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

  • Flag any permit to work we’ll need
  • Send your site hours and access windows
  • Explain the parking and delivery arrangements

Facade sealing in Thames Ditton: the local picture

The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack. Thames Ditton has plenty of hotels close by, all within 2 miles. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

Hospital estates such as Molesey Community Hospital (to the west of Thames Ditton) tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Hotel extensions and refits, at places such as Mitre Hotel, 1.2 miles north of Thames Ditton, usually run between busy periods, so the sealing is squeezed into short windows. New units and refits on sites such as Fairfield Trade Park, 2 miles to the north-east of Thames Ditton, need their panel and perimeter joints sealed to the specification.
