Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

How we handle mastic sealing in Broad Oak

Across Broad Oak and the rest of Kent, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. Addresses, photos of typical joints and a rough idea of quantities let us give a quick quote or we can visit. If you’re dealing with open joints in brickwork or panels and draught complaints from residents or tenants, we can put it right. For commercial sealant work in Broad Oak, you deal with one contact from quote to sign-off, whether it’s one building or several.

Owners and agents with buildings around smaller places such as Broad Oak tend to manage small terraces of association properties, converted barns and commercial units. Frame and wall-joint mastic on all of them ages and hardens.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we are upfront about that.

Why act early in Broad Oak

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. Halls, stores and units around places like Broad Oak may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Your questions answered

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

Yes, and several blocks can go on one quote. Send the address, photographs of the elevations and your access arrangements, and we’ll give a fixed quote.

Do you cover business parks and estates near Broad Oak, such as Buddy's Retail Park?

Yes, sites like Buddy's Retail Park are within our area, along with the rest of Broad Oak. Send details of the unit and the work through our quote form for a quick quote.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

Do you work in Broad Oak?

Yes. We take on work across Broad Oak.

Do you guarantee the mastic work?

There is a 12-month guarantee on our workmanship, backed by public liability insurance.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Masonry that has broken away beside the joint
  • Materials that need asbestos testing before work

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

Surfaces we seal

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

Should maintenance staff do it?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

Signs you need mastic sealing in Broad Oak

Much failed sealant was laid on dirty, dusty or damp surfaces. Where the faces weren’t cleaned or primed as specified it comes away from one face.

If one of these sounds familiar, it’s time for a closer look:

  • Failed external movement joints
  • Occupiers reporting cold air round windows
  • Cracked, hardened mastic round windows on a block
  • Water getting in round frames after rain

Older community buildings, St Nicholas' Church among them, often have frames of mixed ages whose mastic varies.

Questions to ask before you book

  • Their public liability cover
  • Are they CHAS accredited or on Constructionline?
  • Do they follow the manufacturer’s priming guidance?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Broad Oak are usually 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. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Send your site hours and access windows
  • Send asbestos survey details if the building is pre-2000

Getting a fixed quote

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, speak to us on 01277 525 020 or use the quote form.

Cost factors for mastic joints

These are the things that shape the price:

  • How much there is to seal
  • Phasing around occupants
  • Removal of failed or old sealant
  • Backing rod, priming and other preparation

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

What to include in your enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • Access details, including height
  • Clear photographs of the problem areas
  • Your programme or deadline
  • Whether an asbestos survey exists

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Blocks and managed buildings in Broad Oak

Broad Oak is in the South East, one of the UK’s drier regions. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first. Broad Oak is about 54 miles from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.

If you own or manage units on a site such as Buddy's Retail Park, which lies east of Broad Oak, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Buildings close to stations like Sturry station (to the south-east of Broad Oak) are often flats over shops, with frame mastic to keep sound.

Broad Oak is about 2 miles north-east of Canterbury, in Kent. We cover Broad Oak, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 931 places in Kent, from busy centres to rural villages. For work in that direction, see our London page.
