Mastic sealing in Teston, done properly

On a residential block, the work happens around people’s lives. 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 while we work. If you are dealing with no planned programme for sealant and old repairs sealed over failed mastic, we can put it right, on communal entrances and stairwells, balcony and threshold joints and window and door perimeters on blocks alike. A specialist sealant contractor works differently from a general builder: on jobs in Teston, preparation and product choice get the time they need.

Around smaller places like Teston, 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.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What affects the price in Teston

A fixed quote reflects the actual work. It allows for:

  • Induction, permit and paperwork requirements
  • Quantities, in metres or numbers
  • Removal of failed or old sealant
  • Phasing around occupants

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Sending details for a quote

A few photos plus some basic facts will normally do. It helps to include:

  • The postcode of the building
  • Whether an asbestos survey exists
  • Drawings or a marked-up plan, if available
  • What the building is and how it’s used

Pricing a project or setting a maintenance budget? Send the scope and any drawings, and we will return a fixed quote you can plan around. For a chat about it beforehand, ring 01277 525 020 or use the quote form.

When to call us in Teston

Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. If the joint or the product wasn’t suited to the movement, it splits and fails early.

It’s worth sending us details if you spot any of the following:

  • Cracked, hardened mastic round windows on a block
  • Damaged joints in communal entrances and corridors
  • A mix of products and colours from past repairs
  • Water getting in round frames after rain

Older community buildings, Church of St Peter and St Paul among them, often have frames of mixed ages whose mastic varies.

What your quote should include

  • Will RAMS and insurance details be available?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Proof of insurance
  • Do they follow the manufacturer’s priming guidance?

Our contractor checklist

What sealant work can’t fix

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Leaks through the frame itself rather than the perimeter
  • Masonry that has broken away beside the joint

If you’re not sure, just ring 01277 525 020 or email us and we’ll give you a straight answer.

What we seal

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

Frames, entrances and external joints in Teston

Central London is about 29 miles from Teston. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. Teston 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 elevations facing the sun and the prevailing weather are usually where frame mastic ages first.

If you manage student housing near a university such as University for the Creative Arts - Maidstone, 2.7 miles north-east of Teston, the summer turnaround is the time for mastic. Buildings close to stations like Wateringbury station (0.9 miles south-west of Teston) are often flats over shops, with frame mastic to keep sound.

Teston is about 4 miles west of Maidstone, in Kent. Businesses, contractors and managing agents in Teston use us for work on mastic joints, as part of our coverage of Kent. Across Kent, 931 places are covered, Teston among them. Sites around London have their own page, roughly 29 miles from Teston.

If your building is just outside Teston, we cover Red Hill (1 mile north-west), West Farleigh (1 mile south-east), Wateringbury (1 mile west), Barming Heath (1 mile east) and Hoppers Corner (1 mile east). Further afield, our area takes in Maidstone (4 miles east), Sittingbourne (14 miles north-east), Sevenoaks (11 miles west), Royal Tunbridge Wells (11 miles south-west), Gravesend (12 miles north) and Tonbridge (8 miles south-west).

Common questions from Teston clients

Is Teston too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

We manage a building near Wateringbury station. Can you help?

Yes, and several blocks can go on one quote. We work to your notice and access arrangements.

How many days will you need on site?

It depends on the scope, though a typical visit typically takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we will set out a timescale with the quote.

Do you seal on top of existing sealant?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Can you seal joints high up on a block?

Every block is different. We agree access with you at quote stage so the fixed quote reflects it.

How do you choose the sealant?

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.

Why it’s worth doing now in Teston

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. Converted and older buildings near places like Teston tend to move, and aged sealant cracks. 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 fixed quote.

What you get with us

  • One contact handling all your sites
  • Specification-led, product-correct work
  • A Constructionline member, so easy to vet
  • 12-month guarantee on workmanship

How a job runs

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before the next one starts. Jobs in and around smaller places like Teston are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  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. We strip out the old sealant.
  4. The joints are prepared and resealed with the right product.
  5. Buildings are completed in turn.

Getting the site ready
