Your questions answered

Is High Easter off your patch?

Not at all. High Easter is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work at a site such as Parklands Business Centre, by High Easter?

Yes. Estates, retail parks and business parks around High Easter, Parklands Business Centre among them, are all within reach. A few photographs and the unit address let us price the work.

Do you work with property factors and landlords?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order with dates agreed in advance.

Will you just go over the old sealant?

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

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Do you supply RAMS and insurance details?

Let us know your requirements: tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We hold CHAS accreditation and Constructionline membership.

Mastic sealing in High Easter, done properly

Most buildings come with mastic joints nobody has looked at since handover, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. When it hardens, splits or pulls away, water and draughts follow along with complaints. We work on window and door perimeters on blocks, communal entrances and stairwells and communal kitchens and washrooms, and the usual reasons a site gets in touch are a mix of products and colours from past repairs and damp patches beside frames. A single leaking joint is often how a building in High Easter 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.

Owners and agents with buildings around smaller places such as High Easter 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.

We stand by our work: 12 months, guaranteed. That covers our preparation and application, and we come back if anything isn’t right.

When to bring in a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Mastic sealing around High Easter: what changes locally

High Easter is in the South East, one of the UK’s drier regions. 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. High Easter lies roughly 29 miles out from central London. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres.

Landlords with units on estates such as Parklands Business Centre, 2.6 miles to the west of High Easter, can bring frame, door and external mastic across several units into one programme. Churches, halls and community buildings such as Parish Church of St Mary are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

High Easter is about 7 miles north-west of Chelmsford, in Essex. High Easter sits inside our coverage and the rest of Essex, with the same fixed quotes and 12-month guarantee as everywhere else. High Easter is one of 644 places we cover in Essex for mastic joints. Sites around London have their own page, roughly 29 miles from High Easter.

Business premises anywhere in CM1 are within our area. Streets here include The Street and Boreham Court. Nearby places we also cover include Stagden Cross (1 mile east), High Roding (2 miles north-west), Keeres Green (2 miles west), Roundbush Green (2 miles west) and Great Canfield (2 miles north-west) for mastic joints. Bigger towns within reach include Chelmsford (7 miles south-east), Braintree (10 miles north-east), Harlow (11 miles west), Brentwood (13 miles south), Maldon (15 miles east) and Billericay (13 miles south).

On site: what to expect

Where the site stays busy, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then handed back before the next one starts. For work around High Easter, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. We finish each building before moving to the next.

Before we start on site

  • Tell us which areas need to stay in use
  • Point out parking and an unloading spot
  • Tell staff and tenants when we will be in

Getting a fixed quote

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.

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Failed window or door frames, which need a window contractor
  • Misted or failed double-glazed units
  • Masonry that has broken away beside the joint

If you’re not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

Joints and surfaces we work on

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

Cost factors for mastic joints

Each job is priced on its own details. The things that drive the figure:

  • The size and state of each joint
  • Removal of failed or old sealant
  • Location, for remote and island sites
  • Any access equipment needed

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

Good information means a firmer quote. Helpful details to send:

  • Clear photos of the problem areas
  • Whether the building will be occupied during the work
  • The asbestos register, for older buildings
  • Drawings or a marked-up plan, if available

A handful of photographs and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or email drawings and photos to discuss it first.

How the job changes by surface

Planned maintenance

How long mastic lasts depends on exposure, movement and the product used. Inspecting joints regularly keeps programmes on track.

Window and door perimeters on blocks

Perimeter joints on blocks are best done elevation by elevation or block by block. How each joint is reached is agreed at quote stage.

Keeping the joints sound

For the best life from the joints:

  • Group repairs into a planned programme
  • Track which buildings were done and when
  • Make mastic part of routine maintenance checks
  • Make it easy for occupiers to report draughts

Keep records of when each building was resealed. It helps plan the next round and shows what was done.

Leaks at window perimeters spoil finishes and can affect frames. Early resealing is far simpler than repairs inside.
