About our mastic sealing in Wallington

Older blocks and commercial buildings can have mastic that contains asbestos. We check the asbestos register or survey before any old sealant is cut out and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. Site teams most often ask us about damaged joints in communal entrances and corridors and estate-wide sealant that is simply worn out, on window and door perimeters on blocks, communal entrances and stairwells and external wall and movement joints. Facilities teams, main contractors and managing agents in Wallington tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In a smaller place such as Wallington, landlords and agents tend to look after small blocks, flats over shops, sheltered housing and commercial units. The mastic around their frames and external joints ages like anywhere else.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Quoting for work in Wallington

Quotes vary with the job. Expect it to depend on:

  • Quantities, in metres or numbers
  • Phasing around occupants
  • Which sealant the job calls for
  • Any access equipment needed

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Details that help us quote

The more we know, the firmer the quote. When you get in touch, include:

  • Access details, including height
  • Your programme or deadline
  • Where the site is, with the postcode
  • Drawings or a marked-up plan, if available

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Mastic sealing in Wallington: the local picture

With the shore within about 1 mile, Wallington counts as a coastal location. On buildings near the shore, the side facing the weather usually needs its mastic renewed first, and they deserve more regular inspection. Rainfall across the South East, Wallington included, is lower than in many parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.

For agents with blocks near Fareham station, 1 mile west of Wallington, a block-wide mastic programme deals with frames, balconies and entrances in one go. Trustees of buildings like Parish Church of St Peter and St Paul can bring frame and external mastic into a planned maintenance list. If your remit includes a building such as Wykeham House School, frame and door mastic can be programmed for the holidays.

Wallington is about 1 mile east of Fareham, in Hampshire. Wallington sits inside our coverage and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 723 places in Hampshire.

Work on mastic joints is covered throughout PO16, PO14 and PO17. Buildings on Bath Lane, Drift Road and Osborn Road are within our area.

Work for main contractors and building owners

We work for building owners and managing agents on everything from one building to a spread of sites around Wallington. Several sites can go on one quote, so there’s one set of paperwork to deal with.

If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.

Our process

We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a site in Wallington, we plan so the whole job is done in one go where possible. Clear photos and measurements help us bring the right products.

  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. We agree the programme and dates with you.
  4. Failed sealant is removed and the faces prepared.
  5. Joints are resealed and tooled.
  6. We check the finished work and confirm the guarantee.

Preparing the site

  • Confirm the product named in the specification
  • Agree which areas must stay open
  • Explain the parking and delivery arrangements

Ask for a quote

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Advice

Should maintenance staff do it?

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Different surfaces, different methods

Window and door perimeters on blocks

We normally work through a block’s windows in a planned order. Access is agreed with you before the quote is fixed.

Estate-wide resealing programmes

Consistent products and colours across an estate make future maintenance simpler and easier to manage.

Looking after the joints

To get the most from the new sealant:

  • Share the asbestos register when you send details
  • Start inspections with the most exposed faces
  • Make mastic part of routine maintenance checks
  • Reduce knocks to communal area joints

Where a paintable product was specified, it can be painted after curing. Silicone usually can’t be painted, so keep decorators off it.

Planned resealing is easier to budget than emergency repairs. A programme can start with the worst buildings and work down the list.

Wallington: questions and answers

Does the sea air around Wallington change the choice of sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Is Wallington off your patch?

No. Places such as Wallington are covered as much as the big towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

What guarantee do you give on resealing?

There is a 12-month guarantee on our workmanship, backed by public liability insurance.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
