Mastic sealing near Kent Street

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

What sets the cost

The price varies from site to site. It mainly depends on:

  • Any access equipment needed
  • Induction, permit and paperwork requirements
  • Quantities, in metres or numbers
  • Phasing around occupants

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

What to include in your enquiry

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

  • How the joints are reached, and at what height
  • A wide shot and a close-up of the area
  • Rough lengths or quantities, or drawings if you have them
  • Whether an asbestos survey exists

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.

Mastic sealing for commercial buildings in Kent Street

Different joints need different sealants. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, and MS polymer sealants stick well to many substrates and often take paint. We’ll confirm the colours available for the specified product. We work on balcony and threshold joints, communal entrances and stairwells and communal kitchens and washrooms, and what we’re called in for most is draughts at frames across a block and the same joint failures repeated across a portfolio. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Kent Street it comes down to the same thing: the right product in a properly prepared joint.

In and around smaller places like Kent Street, 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.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Doing it in-house

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Our process

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before we move to the next. Smaller jobs around Kent Street can be grouped with others nearby. 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. 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

  • Let building users know which areas are affected
  • Send asbestos survey details if the building is pre-2000
  • Move anything stored against the joints

Commercial clients in Kent Street

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Kent Street can sit alongside others in a wider programme across Kent.

For owners and agents in Kent Street

Kent Street sits in one of the drier corners of the country, the South East. External mastic still waits for dry faces and the right temperature, while the elevations that take the most sun tend to show hardened mastic first. Kent Street lies roughly 26 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.

Site managers at schools like Kings Hill School can fit frame mastic into the summer works. If you own or manage units on a site such as Kings Hill Business Park, 0.8 miles to the north-east of Kent Street, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Kent Street is about 6 miles west of Maidstone, in Kent. If you are looking for mastic sealing in Kent Street, we can help. Our Kent coverage takes in 931 places, large and small. We also cover London, around 26 miles from Kent Street.

We also cover Herne Pound (1 mile south-west), Mereworth (1 mile south), New Pound (1 mile west), Pizien Well (1 mile south-east) and Swanton (1 mile south-west).

Different surfaces, different methods

Communal areas

Communal entrances, stairwells and corridors have joints at door frames, screens, skirting and floor edges. Fresh joints make shared areas look looked after.

Planned maintenance

Adding mastic to planned maintenance avoids reactive repairs and spreads the work.

FAQs: Kent Street

Will you take on a block within reach of Wateringbury station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.

Will you take on work at estates like Kings Hill Business Park, close to Kent Street?

Yes, sites like Kings Hill Business Park are within our area, along with the rest of Kent Street. Send details of the unit and the work through our quote form for a quick quote.

How long does a job like this take?

It depends on the scope, but the work normally takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we’ll set out a timescale with the quote.

Do you supply RAMS and insurance details?

We’re CHAS accredited, a Constructionline member and carry public liability insurance. For specific documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Do you cover Kent Street?

Yes. We take on work across Kent Street.

Can you reseal a whole block or estate?

Yes. We survey and price each building, then work through them in order, and the programme can start with the worst.

Common problems we fix in Kent Street

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

Common reasons buildings call us in:

  • Complaints coming in block by block
  • Brittle perimeter mastic across a building
  • Patchy repairs in mismatched sealant
  • Damp patches beside frames

If you look after a block within reach of Wateringbury station, 2.1 miles south-east of Kent Street, frame and balcony mastic can be renewed on one programme.
