Mastic sealing near Green Hailey

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

When something else is needed

Not every problem is a sealant problem, and we’d rather tell you before you spend money. It won’t fix:

  • Failed window or door frames, which need a window contractor
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Roof leaks, gutters or failed flashings that aren’t sealant joints

If in doubt, give us a call on 01277 525 020 or email a schedule or drawings and we will say what we think.

Surfaces we seal

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

About our mastic sealing in Green Hailey

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. Site teams most often ask us about damaged joints in communal entrances and corridors and complaints coming in block by block, across communal entrances and stairwells, window and door perimeters on blocks and balcony and threshold joints. A specialist sealant contractor works differently from a general builder: on jobs in Green Hailey, preparation and product choice get the time they need.

Owners and agents with buildings around smaller places such as Green Hailey 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.

A 12-month guarantee applies to all our work in Buckinghamshire. If an installation problem shows up, give us a call on 01277 525 020 or email us and we will arrange a return visit.

Questions we’re asked in Green Hailey

Will you take on a block within reach of Monks Risborough station?

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we will quote and plan to suit.

Is Crownfield Industrial Estate, near Green Hailey, within your area?

Yes, sites like Crownfield Industrial Estate are within our area, along with the rest of Green Hailey. Send details of the unit and the work through our quote form for a quick quote.

What guarantee do you give on resealing?

Every building we reseal has a 12-month guarantee. It applies to our workmanship rather than damage or problems with the frames.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Is Green Hailey in your area?

Yes. We cover Green Hailey. To discuss a job, call 01277 525 020 or send photos by email.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

On site: what to expect

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself normally takes one or more days per building, depending on the joint lengths and the access, and our waste is bagged and taken away as we go. If others near Green Hailey need work, visits can be combined. You’ll have a fixed quote before work starts.

  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. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

What we need from you

  • Share your working hours and any access restrictions
  • Send any specification or drawings in advance
  • Share the asbestos register for older buildings

Getting a fixed quote

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.

Advice

When to call us in Green Hailey

Sunlight and weather break mastic down over time. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.

Clients normally get in touch after noticing something like this:

  • Draughts at frames across a block
  • Cracked, hardened mastic round windows on a block
  • No planned programme for sealant
  • Estate-wide sealant that is simply worn out

If you own or manage units on a site such as Crownfield Industrial Estate, which lies south-west of Green Hailey, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Questions to ask before you book

  • How joint depth will be controlled
  • Which product they’ll use, and why it suits the joint
  • Their public liability cover
  • What the guarantee covers, and for how long

Frames, entrances and external joints in Green Hailey

Central London is about 34 miles from Green Hailey. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. Green Hailey sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first.

Trustees of buildings like Church of St Dunstan can bring frame and external mastic into a planned maintenance list. Schools and community buildings such as Monks Risborough CofE Primary School need frame and external mastic kept sound like any building.

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

We work for building owners and managing agents on everything from one building to a spread of sites around Green Hailey. One quote can cover more than one site, which keeps the paperwork simple.

Site staff or a sealant specialist?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

What affects the price in Green Hailey

We price every job individually. The main factors are:

  • Whether old sealant has to be cut out first
  • Any access equipment needed
  • Joint width, depth and condition
  • Specialist products, such as fire-rated or hygienic sealants

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.

Sending details for a quote

Diagnosis starts before we arrive. Let us know:

  • The product your specification calls for
  • Your programme or deadline
  • Clear photographs of the problem areas
  • What the building is and how it’s used

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 photographs and a few notes.
