Mastic sealing in Kimbridge, done properly

Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on shopfronts below residential blocks, balcony and threshold joints and communal kitchens and washrooms, and the failures we’re asked to look at most are no planned programme for sealant and window mastic that has split and shrunk. A single leaking joint is often how a building in Kimbridge first comes to us: we look at the rest while we are there and tell you what we find.

Owners and agents with buildings around smaller places such as Kimbridge tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.

Every job we finish is backed by a 12-month workmanship guarantee, in Kimbridge as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Common problems we fix in Kimbridge

Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.

Most enquiries start with one or more of the following:

  • Mastic failing across several blocks on an estate
  • A mix of products and colours from past repairs
  • Brittle perimeter mastic across a building
  • Open joints in brickwork or panels

Buildings close to stations like Mottisfont & Dunbridge station (to the north-west of Kimbridge) are often flats over shops, with frame mastic to keep sound.

What your quote should include

  • How long is the guarantee, and what does it include?
  • Will RAMS and insurance details be available?
  • Who will actually carry out the work
  • How joint depth will be controlled

How to choose a sealant contractor

Block-wide mastic in Kimbridge

Kimbridge lies roughly 70 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. The South East is one of the drier parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building typically need attention first.

If you are responsible for a building such as Church of St Andrew, frame and door mastic needs the same attention as any other property. If your remit includes a building such as Awbridge Primary School, frame and door mastic can be programmed for the holidays.

Kimbridge is about 3 miles north-west of Romsey, in Hampshire. Across the SO51 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee.

What affects the price in Kimbridge

Before we quote, we look at:

  • Location, for remote and island sites
  • The product specified
  • The total length or number of joints
  • How much existing material needs removing

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What to include in your enquiry

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

  • What the building is and how it’s used
  • Asbestos survey details if the building is older
  • Any dates the work must fit around
  • How the joints are reached, and at what height

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photos and a few notes.

On site: what to expect

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before the next one starts. Rural sites near Kimbridge may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Make sure the joints can be reached
  • Send asbestos survey details if the building is pre-2000
  • Send your site hours and access windows

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or email drawings and photos.

FAQs: Kimbridge

Do you work for managing agents with blocks near Mottisfont & Dunbridge station?

Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Is Kimbridge too small for you to travel to?

Not at all. Kimbridge is within our area. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

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.

How long does a job like this take?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Do you work for managing agents and housing associations?

Yes, block and estate work is a core part of what we do. Buildings are scheduled in turn so you can plan around it.

For managing agents and facilities managers

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.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

Doing it in-house

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 easy to get wrong without experience.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

What we can’t put right

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Failed window or door frames, which need a window contractor
  • Leaks from above rather than through a joint

If you’re not sure, just call the office on 01277 525 020 or send details through our quote form and we will give you a straight answer before you book.

Surfaces we seal

  • Shopfronts below residential blocks
  • External wall and movement joints
  • Communal kitchens and washrooms
  • Balcony and threshold joints
