Mastic sealing for Battersea sites

About our mastic sealing in Battersea

We diagnose before we prescribe: what has failed, what caused it and whether new sealant will actually solve it. Failed mastic is stripped, the faces taken back to sound material, primed where the manufacturer specifies and resealed, with backing rod setting the depth where it’s needed. If you have cracked, hardened mastic round windows on a block and damaged joints in communal entrances and corridors, we can put it right, whatever the surface. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Battersea, preparation and product choice get the time they need.

In a London area such as Battersea, many buildings are blocks of flats or mixed-use buildings run by managing agents, landlords or housing associations. Window and door perimeters, balcony joints and communal areas all have mastic that ages together across a building.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Battersea: questions and answers

Do you work in occupied care homes around Battersea?

Yes. Care settings are planned area by area, at times agreed with the home. We follow the home’s own procedures throughout.

Do you work in London buildings with loading restrictions?

Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method. The ULEZ covers the whole of Greater London, which we allow for

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How long will the new sealant last?

Nobody can honestly give a figure in years, 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.

Do you do block-wide mastic programmes?

Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

Do you work with property factors and landlords?

Yes. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

What paperwork can you provide?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership.

When something else is needed

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • Leaks through the frame itself rather than the perimeter
  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Broken glass or failed sealed units

Not sure which it is? You can call the office on 01277 525 020 or email a schedule or drawings and we’ll tell you honestly before you book.

What we seal

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

Why act early in Battersea

Looking at mastic during planned maintenance costs little. Waiting until leaks appear means working under pressure with less control over timing. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Why choose Mastic Doctor in Battersea

  • Sealing commercial buildings since 2005
  • Constructionline member for supplier checks
  • Colour options checked against the specified product
  • Specification-led, product-correct work

Read what affects the cost and our accreditations.

Keeping the joints sound

To get the most from the new sealant:

  • Start inspections with the most exposed faces
  • Make mastic part of routine maintenance checks
  • Share your contractor requirements early
  • Plan resealing building by building rather than complaint by complaint

Protect entrance and corridor joints from knocks where possible. Damage at low level is the most common reason communal joints fail early.

Mastic fails gradually, then all at once in a wet spell. Acting at the first signs keeps it a straightforward reseal and saves internal repairs.

How the job changes by surface

Estate-wide resealing programmes

Using the same products throughout keeps the estate consistent and easier to manage.

Commercial and mixed-use buildings

Commercial occupiers normally stay open during the work so the work is phased.

Mastic sealing around Battersea: how the place shapes the job

Battersea has three care or nursing homes no more than 2 miles away. Owners of care premises can bring window and door mastic into a phased programme planned around the home. London blocks come with residents to inform, access to agree and often a concierge or estate office to work with. We plan around the notices and access you arrange.

Student accommodation around universities such as Royal College of Art, 1.1 miles to the north of Battersea, is normally managed block by block, which suits a planned mastic programme. For agents with blocks near Clapham Junction station, less than half a mile to the west of Battersea, a block-wide mastic programme deals with frames, balconies and entrances in one go.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a job in Battersea, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Send the building rules and access times with your enquiry.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  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.

Do you need mastic sealing in Battersea?

In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Regular cleaning wears them further.

It’s worth sending us details if you spot any of the following:

  • Worn sealant at communal door frames
  • Brittle perimeter mastic across a building
  • Occupiers reporting cold air round windows
  • Old repairs sealed over failed mastic

Churches, halls and community buildings such as Clapham Welsh Presbyterian Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

What your quote should include

  • Can the work be phased to keep areas open?
  • What level of public liability insurance do they hold?
  • Do they follow the manufacturer’s priming guidance?
  • Their pre-qualification and accreditations
