Mastic sealing across Milton Common

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Why deal with it now?

Reacting to every complaint means sending someone out block by block. A planned programme treats each building once, under a single quote and a single programme. One visit to deal with every failing joint makes more sense than several trips to a place like Milton Common. Photos of every joint help us quote for the whole job.

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 and we will explain how it’s made up.

Why us?

  • Old sealant cut out, never sealed over
  • Our applicators hold CSCS cards
  • RAL and finish matching where the product range allows
  • A range of standard colours, depending on the product

Mastic sealing for commercial buildings in Milton Common

Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Our applicators are CSCS-carded and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. If you are dealing with no planned programme for sealant and cracked, hardened mastic round windows on a block, we can help. Facilities teams, main contractors and managing agents in Milton Common tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Rural conversions near places like Milton Common often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

Block-wide mastic in Milton Common

At about 44 miles from central London, Milton Common is within reach of the capital. Managed blocks of flats are a big part of commuter-belt property. Milton Common sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and south- and west-facing elevations, which take the most sun and rain, often age first.

Older community buildings, Church of St Helen among them, often have frames of mixed ages whose mastic varies. With historic buildings such as Adwell House, 3.8 miles south-east of Milton Common, in the wider area, owners of older properties around Milton Common should expect mastic to need a product that suits old masonry.

Common problems we fix in Milton Common

UV and rain age external sealant. It stiffens, stops stretching and cracks, especially on south and west faces.

Common reasons buildings call us in:

  • No planned programme for sealant
  • Old repairs sealed over failed mastic
  • Draught complaints from residents or tenants
  • Failed external movement joints

For owners of several units at places like Camp Industrial Estate (under half a mile east of Milton Common), one programme can deal with frame and external mastic across the lot.

Questions to ask before you book

  • Will CSCS-carded applicators be on site?
  • How they’ll work around occupants
  • Which product they’ll use, and why it suits the joint
  • Their pre-qualification and accreditations

Questions to ask before you appoint anyone

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Materials that need asbestos testing before work
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Water coming in from the roof or rainwater goods

If you are not sure, just speak to us on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer.

Surfaces we seal

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

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. For work around Milton Common, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Completed joints are inspected and carry a 12-month workmanship guarantee.

Before we start on site

  • Send your site hours and access windows
  • Explain the parking and delivery arrangements
  • For older buildings, check the asbestos register before work

Request 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 will arrange a site visit.

What the job involves on each surface

Commercial and mixed-use buildings

Mixed-use buildings combine shops below with flats or offices above, so phasing has to suit both. We plan around the site hours and access windows you give us.

Planned maintenance

Mastic wears out like any building component; how fast comes down to movement, weather, UV and the product. Inspecting joints regularly keeps programmes on track.

Questions we’re asked in Milton Common

Is Camp Industrial Estate, near Milton Common, within your area?

Yes. Estates, retail parks and business parks around Milton Common, Camp Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Is Milton Common too small for you to travel to?

Not at all: smaller places are covered as well as towns. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you seal joints high up on a block?

We talk through access for each building when we quote. Tell us the building height and any access already in place and we’ll confirm the approach in the quote.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

How do you handle work on occupied blocks?

The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What do you charge?

Each job is quoted on its own details. To get one, phone 01277 525 020 or use the quote form with a description of the work.

Cost factors for mastic joints

These are the things that shape the price:

  • Whether the work must be split into stages
  • Location, for remote and island sites
  • Induction, permit and paperwork requirements
  • Access and working height

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

What we need to price the job

However big the job, the same details help:

  • Photos of the joints, close up and from further back
  • The product your specification calls for
  • How the joints are reached, and at what height
  • Rough lengths or quantities, or drawings if you have them

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or speak to us on 01277 525 020 or email drawings and photos to discuss it first.
