Mastic sealing in Whistley Green

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. Most enquiries involve damp patches beside frames and the same joint failures repeated across a portfolio, across window and door perimeters on blocks, balcony and threshold joints and shopfronts below residential blocks. Whoever orders the work in Whistley Green, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In and around smaller places like Whistley Green, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

How a job runs

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Whistley Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. We check the asbestos register for older buildings and look at the joints.
  2. The products and programme are set out in a fixed quote.
  3. We strip out the old sealant.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • Explain the parking and delivery arrangements
  • Point out any areas we must not close

Quotes

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Why it’s worth doing now in Whistley Green

Draughts round window perimeters cost occupiers comfort, and they often blame the windows. In many cases, new perimeter sealant deals with it when the frames themselves are sound. Older rural buildings around Whistley Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

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’ll put a fixed figure on it.

What you get with us

  • Colours confirmed for the specified product
  • Work carried out by CSCS-carded applicators
  • A range of standard colours, depending on the product
  • A Constructionline member, so easy to vet

What we can’t put right

Honesty saves time and money. Fresh joints won’t solve:

  • Misted or failed double-glazed units
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first

If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

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

Planned maintenance

We can work into your cyclical maintenance plan, building by building.

Commercial and mixed-use buildings

Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. We work across portfolios on a planned basis.

Keeping the joints sound

To get the most from the new sealant:

  • Share your contractor requirements early
  • Reduce knocks to communal area joints
  • Plan resealing building by building rather than complaint by complaint
  • Track which buildings were done and when

Log the date and extent of the resealing for each block. That makes future programmes easier to plan and shows what was done.

Budgets are easier to plan when sealant is part of planned maintenance. A programme can start with the worst buildings and work down the list.

What affects the price in Whistley Green

Each job is priced on its own details. The things that drive the figure:

  • Phasing around occupants
  • Which sealant the job calls for
  • Any access equipment needed
  • Joint width, depth and condition

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • The asbestos register, for older buildings
  • The type of building and who uses it
  • Drawings or a marked-up plan, if available
  • Clear photographs of the problem areas

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to give us a call on 01277 525 020 or email drawings and photos with what you know.
