How we handle mastic sealing in Erriottwood

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. A planned, building-by-building programme often works better than reacting to each complaint and we quote and schedule each building in turn. If you are dealing with window mastic that has split and shrunk and estate-wide sealant that is simply worn out, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Erriottwood, that means joint design, primers and backing rod as standard.

Owners and agents with buildings around smaller places such as Erriottwood tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Questions we’re asked in Erriottwood

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

Yes. Managing agents, landlords, property factors and housing associations are who this service is for. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Is Erriottwood too far out for you?

No. Places such as Erriottwood are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

What if the old mastic contains asbestos?

Asbestos removal isn’t part of our work. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.

How do you handle work on occupied blocks?

We plan around people living or working in the building. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.

Is mastic sealing guaranteed?

Our workmanship carries a 12-month guarantee, backed by public liability insurance.

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

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

Do you do block-wide mastic programmes?

Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Frames that are rotten, warped or broken
  • Broken glass or failed sealed units
  • Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)

Not sure which it is? You can ring 01277 525 020 or email us and we will tell you honestly.

Where we work in Erriottwood

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

Surface by surface

Window and door perimeters on blocks

Frames vary from uPVC to aluminium and timber, and the product is matched to the frame material and the masonry. Colours are confirmed for the product used.

Commercial and mixed-use buildings

Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. A planned programme suits multi-building portfolios.

Why act early in Erriottwood

Piecemeal repairs over the years often leave mismatched sealant. A block-wide reseal gives one product, one colour and one guarantee and one 12-month guarantee. One visit to deal with every failing joint makes more sense than several trips to a place like Erriottwood. Photos of every joint help us quote for the whole job.

A quote for mastic joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

Why appoint us

  • One number for every site we cover
  • Coloured sealants to suit the setting, where available
  • RAL and finish matching where the product range allows
  • Colour options checked against the specified product

Common problems we fix in Erriottwood

Poor preparation explains many failed joints. Where the faces weren’t cleaned or primed as specified, the bead peels off one side.

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

  • Patchy repairs in mismatched sealant
  • Brittle perimeter mastic across a building
  • Failed external movement joints
  • Communal area joints that look neglected

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

  • Whether old or failed sealant will be cut out, not overlaid
  • Do they follow the manufacturer’s priming guidance?
  • The named product and why it was chosen
  • Their plan for phasing and protecting the area

Frames, entrances and external joints in Erriottwood

Erriottwood is in the South East, one of the UK’s drier regions. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building usually need attention first. Central London is about 40 miles from Erriottwood. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres, and window and balcony mastic on them tends to age at the same rate.

Historic properties like Belmont House and Gardens, 3.4 miles to the south-east of Erriottwood, show the age of some local stock, where frame mastic must suit soft brick or stone. Blocks of flats and mixed-use buildings often cluster around stations such as Teynham station (to the north-east of Erriottwood) and their window and balcony mastic tends to age at the same rate across a building.

Erriottwood is about 4 miles south-east of Sittingbourne, in Kent. Anywhere in ME9, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 931 places in Kent. Sites around London have their own page, roughly 40 miles from Erriottwood.

Commercial sites across ME9 are covered for mastic joints. Among the streets we cover are Christophers Row and Kingsdown Road. Nearby places we also cover include Kingsdown (1 mile west), Lynsted (1 mile north), Newbury (1 mile north-west), Bapchild (1 mile north-west) and Bogle (1 mile north) for mastic joints. A short drive away, we cover Maidstone (11 miles west), Ashford (12 miles south), Canterbury (13 miles east), Sittingbourne (4 miles north-west), Whitstable (11 miles east) and Faversham (5 miles east).

Our process

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. Jobs in and around smaller places like Erriottwood are normally planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. First we look at the mastic on each building and note what needs replacing.
  2. A fixed quote follows, split by block or building if that suits you.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Finished joints are looked over and the 12-month guarantee confirmed.

Before we start on site

  • Explain the parking and delivery arrangements
  • Let building users know which areas are affected
  • Make sure the joints can be reached

Advice

How the quote is worked out

We price every job individually. The things that drive the figure:

  • Induction, permit and paperwork requirements
  • Distance, for remote addresses
  • Specialist products, such as fire-rated or hygienic sealants
  • The size and state of each joint

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote once you have the details.

Sending details for a quote

However big the job, these details speed things up:

  • Whether an asbestos survey exists
  • Whether the building will be occupied during the work
  • Clear photos of the problem areas
  • Your programme or deadline

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, phone 01277 525 020 or send photos by email.
