Mastic sealing in Ridley

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

Cost factors for mastic joints

Quotes vary with the job. Expect it to depend on:

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

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.

Sending details for a quote

We can often quote from photos and a few details. It helps to include:

  • Whether the building will be occupied during the work
  • When you need the work done
  • Asbestos survey details if the building is older
  • The postcode of the building

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, ring 01277 525 020 or email drawings and photos.

How we handle mastic sealing in Ridley

Mastic Doctor has sealed joints on commercial and residential blocks since 2005. Every applicator holds a CSCS card, and the work is backed by public liability insurance. Resealed mastic joints in Ridley carry our 12-month guarantee. We work on window and door perimeters on blocks, balcony and threshold joints and communal kitchens and washrooms, and the usual reasons a site gets in touch are leaks at window and door perimeters and window mastic that has split and shrunk. A single leaking joint is often how a building in Ridley first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places like Ridley, 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.

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.

What the job involves on each surface

Planned maintenance

Adding mastic to planned maintenance avoids reactive repairs and keeps budgets predictable.

External movement joints

The joint width has to suit the movement and the sealant’s capability with the width-to-depth ratio set as the manufacturer advises.

Your questions answered

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

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Photos of each elevation help us quote accurately.

Will you take on work at estates like Bowes Industrial Centre, close to Ridley?

Yes. Our area takes in Ridley and its surroundings, with estates and business parks such as Bowes Industrial Centre included. A few photographs and the unit address let us price the work.

Do you seal on top of existing sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

Do you do block-wide mastic programmes?

Block-wide and estate programmes are common. The quote can be split however suits your budgeting.

Do you check for asbestos in old sealant?

In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.

What paperwork can you provide?

We are 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’ll confirm with the quote.

Block-wide mastic in Ridley

Ridley lies roughly 21 miles out from central London. Managed blocks of flats are a big part of commuter-belt property, and window and balcony mastic on them tends to age at the same rate. Ridley is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first.

Churches, halls and community buildings such as Church of Saint Peter are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Blocks of flats and mixed-use buildings often cluster around stations such as Meopham station (to the north-east of Ridley) and their window and balcony mastic tends to age at the same rate across a building. If you own or manage units on a site such as Bowes Industrial Centre (1.3 miles east of Ridley), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Ridley is about 6 miles south of Northfleet, in Kent. Ridley sits inside our coverage and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 931 places across Kent fall within our area, Ridley among them. Our London page has more on work in that area (21 miles or so).

Business premises anywhere in TN15 are within our area. If your building is just outside Ridley, we cover New Street (1 mile east), Hodsoll Street (1 mile south), South Street (1 mile east), New Ash Green (1 mile north-west) and Culverstone Green (2 miles south-east). Bigger towns within reach include Maidstone (11 miles south-east), Dartford (8 miles north-west), Sevenoaks (8 miles south-west), Royal Tunbridge Wells (15 miles south), Gravesend (6 miles north-east) and Tonbridge (11 miles south).

Our process

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Ridley may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

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

What we need from you

  • Send asbestos survey details if the building is pre-2000
  • Explain the parking and delivery arrangements
  • Tell us your opening times and when work is allowed

Related advice

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

Building owners and managing agents use us on sealant work across single buildings or whole portfolios around Ridley. One quote can cover more than one site, which keeps the paperwork simple.

When to bring in a specialist

Using site staff can make sense for a small touch-up, 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. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

When something else is needed

Some faults sit outside our scope, and we say so rather than covering them up:

  • Roof leaks, gutters or failed flashings that aren’t sealant joints
  • Old mastic suspected of containing asbestos, which must be tested and dealt with by a specialist first
  • Frames that are rotten, warped or broken

If you’re not sure, just speak to us on 01277 525 020 or email drawings and photos and we will give you a straight answer.

What we seal

  • Window and door perimeters on blocks
  • Shopfronts below residential blocks
  • Communal entrances and stairwells
  • Communal kitchens and washrooms
