When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. You’ll hear from us if the cause turns out to be one of these:

  • Frames that are rotten, warped or broken
  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Water coming in from the roof or rainwater goods

If you are not sure, just give us a call on 01277 525 020 or send details through our quote form and we will give you a straight answer.

Where we work in Chignall Smealy

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

Why act early in Chignall Smealy

Replacing mastic before water gets in is a planned job. After water has got in, there may be damp, damaged plaster or decoration to put right too, and the complaints come with it. For buildings around smaller places like Chignall Smealy, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.

Why us?

  • Constructionline member for supplier checks
  • Specification-led, product-correct work
  • Matching to RAL references, product permitting
  • Workmanship guaranteed for 12 months

Site staff or a sealant specialist?

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

What affects the price in Chignall Smealy

A fixed quote reflects the actual work. It allows for:

  • Whether the work must be split into stages
  • Whether old sealant has to be cut out first
  • Quantities, in metres or numbers
  • Travel to remote or island sites

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • The asbestos register, for older buildings
  • Access details, including height
  • Any dates the work must fit around
  • Rough lengths or quantities, or drawings if you have them

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Frames, entrances and external joints in Chignall Smealy

Central London is about 29 miles from Chignall Smealy. Within reach of London, blocks run by agents and associations are common around stations, and window and balcony mastic on them tends to age at the same rate. The South East is one of the drier parts of the UK. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building normally need attention first.

For agents with blocks near Chelmsford station (3.6 miles south-east of Chignall Smealy), a block-wide mastic programme deals with frames, balconies and entrances in one go. Churches, halls and community buildings such as Church of St Nicholas are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time. Historic properties like Hylands (4.7 miles south of Chignall Smealy) show the age of some local stock, where frame mastic must suit soft brick or stone.

Chignall Smealy is about 4 miles north-west of Chelmsford, in Essex.

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Hotels, schools, healthcare sites, offices and retail units book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Diagnose, treat, sign off

Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. Smaller jobs around Chignall Smealy can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We inspect each building and record the joints that have failed.
  2. The quote is fixed and split as suits you.
  3. We agree the programme and dates with you.
  4. Old mastic is removed and the joint faces prepared.
  5. New sealant goes in with backing rod and primer where needed.
  6. Each building is checked and signed off with the 12-month guarantee.

Before we start on site

  • Tell staff and tenants when we will be in
  • Explain the parking and delivery arrangements
  • Make sure the joints can be reached

Common questions from Chignall Smealy clients

Do you work for managing agents with blocks near Chelmsford station?

Yes. Blocks of any size are within what we do. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

Do you take on block-wide or estate-wide mastic work in Chignall Smealy?

Yes, we quote for single buildings and for programmes across several blocks. Residents are given notice through you, and the work moves building by building.

How long does a job like this take?

That varies with the scale of the job, though a typical visit normally takes a few days for most blocks, with larger programmes scheduled building by building. For bigger or phased jobs, we will set out a timescale with the quote.

Can you seal joints high up on a block?

Every block is different. We agree access with you at quote stage so the fixed quote reflects it.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Do you check for asbestos in old sealant?

In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
