Mastic sealing for commercial buildings in Great Stonar

Blocks are lived in, so access and disruption have to be thought through. Dates, areas and the order of work are agreed with you in advance, giving you what you need to notify residents. Entrances and stairwells are kept in use throughout. We work on shopfronts below residential blocks, communal kitchens and washrooms and window and door perimeters on blocks, and the failures we are asked to look at most are communal area joints that look neglected and no planned programme for sealant. Searching for sealant specialists in Great Stonar? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

Rural conversions near places like Great Stonar 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.

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

Mastic sealing around Great Stonar: how the place shapes the job

The sea is no more than about 2 miles from Great Stonar. On buildings near the shore, the side facing the weather typically needs its mastic renewed first; plan inspections around that. At about 64 miles from central London, Great Stonar is within reach of the capital. Within reach of London, blocks run by agents and associations are common around stations.

Property owners at sites such as Birnham Farm Business Centre, 2.9 miles south-west of Great Stonar, can have mastic renewed between lettings. Churches, halls and community buildings such as St Mary's Church are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Great Stonar is about 5 miles south-west of Ramsgate, in Kent. We cover commercial sites throughout Great Stonar. Our Kent coverage takes in 931 places, from busy centres to rural villages. For work in that direction, see our London page, about 64 miles away.

Should maintenance staff do it?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Questions we’re asked in Great Stonar

Does the sea air around Great Stonar change the choice of sealant?

It can. Coastal exposure works external joints harder than inland weather. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Is Great Stonar too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

How do you reach windows on upper floors?

Access is discussed and agreed before the quote is fixed. Tell us the building height and any access already in place and we will confirm the approach in the quote.

How do I request a quote?

The quote form is the simplest route, though you can also call 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the 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.

From enquiry to sign-off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work typically takes a few days for most blocks, with larger programmes scheduled building by building. If others near Great Stonar need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  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. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  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.

Preparing the site

  • For older buildings, check the asbestos register before work
  • Point out any areas we must not close
  • Tell us your opening times and when work is allowed

Request a quote

Let us know the site, the scope and your timescale, and we will put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or send details through our quote form.

What affects the price in Great Stonar

Before we quote, we look at:

  • Joint width, depth and condition
  • The product specified
  • Removal of failed or old sealant
  • How accessible the joints are

The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • The type of building and who uses it
  • When you need the work done
  • The product your specification calls for
  • The asbestos register, for older buildings

The quickest route to a quote is a few photographs and the site postcode. Send them through the quote form, or phone 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Asbestos-containing sealant, which we don’t remove
  • Masonry that has broken away beside the joint
  • Misted or failed double-glazed units

If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Joints and surfaces we work on

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

Do you need mastic sealing in Great Stonar?

Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.

Site and facilities staff are often the first to spot these:

  • Complaints coming in block by block
  • Damp patches beside frames
  • Estate-wide sealant that is simply worn out
  • Movement joints with sealant missing

If your remit includes a building such as Sandwich Infant School, frame and door mastic can be programmed for the holidays.

What to look for in a quote

  • Is the sealant right for the movement and the substrate?
  • How the existing material will be dealt with
  • How they handle RAMS and site documents
  • Are they CHAS accredited or on Constructionline?
