Mastic sealing for businesses in Bluetown

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Surface by surface

Tenement and older buildings

Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.

Window and door perimeters on blocks

Blocks have a mix of frame materials, and the product is matched to the frame material and the masonry. We’ll confirm the colours available for the specified product.

About our mastic sealing in Bluetown

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint, with each block quoted and scheduled in turn. If you are dealing with water getting in round frames after rain and worn sealant at communal door frames, we can put it right, on balcony and threshold joints, shopfronts below residential blocks and external wall and movement joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Bluetown, preparation and product choice get the time they need.

Around smaller places like Bluetown, older walls fitted with newer windows are a familiar sight. Perimeter mastic there has to grip an uneven face and suit the building’s character.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Looking after buildings in and around Bluetown

Bluetown sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first. Central London is about 39 miles from Bluetown. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.

Student blocks close to universities like Canterbury Christ Church University, 3.3 miles south-west of Bluetown, are easiest to work on between tenancies. If your remit includes a building such as Milstead and Frinsted Church of England Primary School, frame and door mastic can be programmed for the holidays. Trustees of buildings like Church of St Catherine can bring frame and external mastic into a planned maintenance list.

Bluetown is about 4 miles south of Sittingbourne, in Kent.

Questions we are asked in Bluetown

Is Bluetown too far out for you?

Not at all. Bluetown is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you work for managing agents with blocks near Sittingbourne station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we will give a fixed quote.

How many days will you need on site?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

Do you supply RAMS and insurance details?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Why act early in Bluetown

Dealing with failed joints one report at a time is slow and scattered. A planned programme treats each building once, under a single quote and a single programme. Older rural buildings around Bluetown move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Cost follows what’s involved: 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 clients in Bluetown choose us

General trades versus a specialist

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Diagnose, treat, sign off

When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking a few days for most blocks, with larger programmes scheduled building by building. Rural sites near Bluetown may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  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. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Preparing the site

  • Send any specification or drawings in advance
  • Let us know about inductions and permits
  • Share your working hours and any access restrictions

Getting a fixed quote

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

Keeping the joints sound

Keep the joints in good shape with a few simple steps:

  • Include mastic in your cyclical inspections
  • Ask residents or tenants to report leaks and draughts early
  • Prioritise elevations facing the weather
  • Have the asbestos survey to hand for older buildings

Ask residents or tenants to report draughts or leaks round windows early. Early reports catch failures before damage spreads.

Planned resealing is easier to budget than emergency repairs. We can quote buildings in priority order and work down the list.

How the quote is worked out

To price the job, we consider:

  • Whether old sealant has to be cut out first
  • Backing rod, priming and other preparation
  • Distance, for remote addresses
  • Induction, permit and paperwork requirements

A quote for mastic joints depends on how many there are, their condition and the access. Call for a quote.

What to include in your enquiry

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Whether the building will be occupied during the work
  • The site address and postcode
  • A wide shot and a close-up of the area
  • How the joints are reached, and at what height

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 photos and a few notes.
