About our mastic sealing in Upper Hardres

For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. If you have window mastic that has split and shrunk and draughts at frames across a block, we can put it right. Most enquiries from Upper Hardres start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Owners and agents with buildings around smaller places such as Upper Hardres 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: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

From enquiry to sign-off

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Upper Hardres are usually planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  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. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Tell staff and tenants when we will be in
  • Confirm the product named in the specification
  • Arrange parking or a loading space

FAQs: Upper Hardres

Can one quote cover a number of our buildings near Upper Hardres?

Yes, we quote for single buildings and for programmes across several blocks. Send the addresses and photos and we will give a fixed quote.

Is Upper Hardres too small for you to travel to?

No. Places such as Upper Hardres are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Is mastic sealing guaranteed?

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

How do you handle work on occupied blocks?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.

How do you reach windows on upper floors?

It depends on the building. We agree access with you at quote stage so the fixed quote reflects it.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.

Does the weather affect the work?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

How the job changes by surface

Tenement and older buildings

Stone needs a neutral-cure product, so we pick a grade that won’t mark it.

Estate-wide resealing programmes

Using the same products throughout keeps the estate consistent.

What we can’t put right

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Failed window or door frames, which need a window contractor
  • Broken glass or failed sealed units
  • Leaks from above rather than through a joint

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

  • External wall and movement joints

Block-wide mastic in Upper Hardres

Upper Hardres lies roughly 54 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate. Upper Hardres sits in one of the drier corners of the country, the South East. 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.

If you manage student housing near a university such as University for the Creative Arts, 4.1 miles north of Upper Hardres, the summer turnaround is the time for mastic. If you’re responsible for a building such as Church of St Peter and St Paul, frame and door mastic needs the same attention as any other property. Blocks of flats and mixed-use buildings often cluster around stations such as Bekesbourne station, 3.9 miles to the north-east of Upper Hardres, and their window and balcony mastic tends to age at the same rate across a building.

Upper Hardres is about 4 miles south of Canterbury, in Kent. Upper Hardres sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. 931 places across Kent fall within our area, including Upper Hardres. For work in that direction, see our London page.

Why deal with it now?

Mixed repairs by different contractors leave a patchwork of products and colours. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. Converted and older buildings near places like Upper Hardres tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we’ll explain how it’s made up.

When to bring in a specialist

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

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

After the work

After handover, these steps help:

  • Mention RAMS, insurance or CSCS requirements up front
  • Include mastic in your cyclical inspections
  • Share the asbestos register when you send details
  • Encourage occupiers to report problems at frames

Include sealant in planned building inspections. Check for splits, open joints, brittle mastic and lifting edges and record where they are.

Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.
