What the job involves on each surface

Estate-wide resealing programmes

An estate of similar buildings suits a rolling programme. Each block is priced and scheduled in order.

Planned maintenance

Planned resealing replaces emergency callouts and keeps budgets predictable.

Mastic sealing in Thames Ditton, done properly

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. We work on communal kitchens and washrooms, window and door perimeters on blocks and shopfronts below residential blocks, and the failures we are asked to look at most are estate-wide sealant that is simply worn out and damaged joints in communal entrances and corridors. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Thames Ditton it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.

For landlords and associations with stock in and around Thames Ditton, grouping buildings into one visit saves travel. One quote can cover a whole list of addresses.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

From enquiry to sign-off

At the end of each section, we remove the tape, clean down and inspect every joint 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 job in Thames Ditton, the main thing is a clear picture of the work, so send photographs of each area. You will then get a fixed price for the work.

  1. We inspect each building and record the joints that have failed.
  2. You get a fixed quote, per block or for the whole programme.
  3. Dates and areas are agreed so occupiers can be told.
  4. Failed sealant is removed and the faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. We check the finished work and confirm the guarantee.

Before we start on site

  • Move anything stored against the joints
  • Warn occupants and staff about the work
  • Confirm the product named in the specification

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Masonry that has broken away beside the joint
  • Leaks from above rather than through a joint
  • Failed window or door frames, which need a window contractor

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

Surfaces we seal

  • Balcony and threshold joints
  • Communal entrances and stairwells
  • Window and door perimeters on blocks
  • Shopfronts below residential blocks
  • External wall and movement joints
  • Communal kitchens and washrooms

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Thames Ditton: questions and answers

Can you work in a care home near Thames Ditton with residents in?

Yes, with the manager deciding the order and timing of rooms. Tell us about any infection-control or safeguarding requirements and we will work to them.

Do you work for managing agents with blocks near Thames Ditton station?

Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

What about access for upper-floor joints?

It depends on the building. How upper joints are reached is agreed before work is booked so there are no surprises.

Do you supply RAMS and insurance details?

We’re CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

What guarantee do you give on resealing?

Our workmanship carries a 12-month guarantee and we hold public liability insurance.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Common problems we fix in Thames Ditton

Many failed joints were sealed without backing rod, so the mastic is glued to the joint bottom too. That three-sided adhesion stops it stretching and it tears.

Site and facilities staff are often the first to spot these:

  • Old repairs sealed over failed mastic
  • Complaints coming in block by block
  • Communal area joints that look neglected
  • Draught complaints from residents or tenants

Buildings close to stations like Thames Ditton station, under half a mile to the west of Thames Ditton, are often flats over shops, with frame mastic to keep sound.
