Mastic sealing in Kingston: the local picture

The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and elevations facing the sun and the prevailing weather are usually where frame mastic ages first. Kingston has two care or nursing homes no more than 2 miles away. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.

Trustees of buildings like Church of St Mary can bring frame and external mastic into a planned maintenance list. Owners of student blocks near The Open University, 1.3 miles south-west of Kingston, can schedule frame and external mastic for the summer vacation.

Mastic sealing in Kingston

Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: it sits round windows and doors, along external joints and through communal areas. When it hardens, splits or pulls away, water and draughts follow, and occupiers start reporting it. We work on communal entrances and stairwells, window and door perimeters on blocks and communal kitchens and washrooms, and what we are called in for most is a mix of products and colours from past repairs and damaged joints in communal entrances and corridors. A specialist sealant contractor works differently from a general builder: in Kingston, that means joint design, primers and backing rod as standard.

Converted and older buildings in and around Kingston often put modern windows into old walls. Perimeter joints need a sealant that suits both frame and masonry.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

What affects the price in Kingston

A fixed quote reflects the actual work. It takes account of:

  • Any access equipment needed
  • Whether old sealant has to be cut out first
  • Location, for remote and island sites
  • Which sealant the job calls for

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

What to include in your enquiry

It doesn’t need to be a full survey. These details are enough to start:

  • The type of building and who uses it
  • Drawings or a marked-up plan, if available
  • Asbestos survey details if the building is older
  • Any specification or named product

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, ring 01277 525 020 or email us.

Keeping the joints sound

After handover, a little attention goes a long way:

  • Make it easy for occupiers to report draughts
  • Reduce knocks to communal area joints
  • Plan resealing building by building rather than complaint by complaint
  • Track which buildings were done and when

Keep bins, bikes and deliveries away from low-level joints where you can. Knocks cause many early failures in communal areas.

Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.

Doing it in-house

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

On site: what to expect

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Work in places the size of Kingston is planned as a single visit where we can. Clear photographs and measurements help us bring the right products.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Preparing the site

  • Point out parking and an unloading spot
  • Tell us what induction or permit system the site runs
  • Have the specification and drawings to hand

Advice

Questions we’re asked in Kingston

Do you work for managing agents with blocks near Woburn Sands station?

Yes. Blocks of any size are within what we do. Send the address, photographs of the elevations and your access arrangements, and we will give a fixed quote.

Can you work at a site such as Wavendon Business Park, by Kingston?

Yes, sites like Wavendon Business Park are within our area, along with the rest of Kingston. Send details of the unit and the work through our quote form for a quick quote.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. You’ll have an expected duration with the quote.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you supply RAMS and insurance details?

Our credentials include CHAS, Constructionline and public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Do you work for managing agents and housing associations?

Yes. Most of our mastic sealing is for agents, factors, housing associations and portfolio landlords, and we quote building by building or as a programme.

Owners, agents and contractors

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

If you look after buildings for someone else, clear figures and clear communication matter. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

What we are called out for in Kingston

Buildings move with temperature and moisture, and the sealant takes up that movement. If the joint or the product wasn’t suited to the movement, it splits long before it should.

Any of the following is a good reason to get the joints checked over:

  • Worn sealant at communal door frames
  • Old repairs sealed over failed mastic
  • Open joints in brickwork or panels
  • Water getting in round frames after rain

Blocks of flats and mixed-use buildings often cluster around stations such as Woburn Sands station (to the south-east of Kingston) and their window and balcony mastic tends to age at the same rate across a building.

What to look for in a quote

  • Which product they’ll use, and why it suits the joint
  • Will CSCS-carded applicators be on site?
  • Do they follow the manufacturer’s priming guidance?
  • What the guarantee covers, and for how long
