Mastic sealing for businesses in Stratford St Mary

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. If others near Stratford St Mary need work, visits can be combined. You will have a fixed quote before work starts.

  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. Failed mastic is removed completely.
  4. Joint faces are cleaned, backed and resealed.
  5. Buildings are completed in turn.

Before we start on site

  • Confirm the product named in the specification
  • Let building users know which areas are affected
  • Explain the parking and delivery arrangements

Advice

Mastic sealing in Stratford St Mary, done properly

Managing agents and housing associations usually need paperwork before anyone starts. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member, with public liability insurance. Most enquiries involve cracked, hardened mastic round windows on a block and worn sealant at communal door frames, across window and door perimeters on blocks, communal entrances and stairwells and shopfronts below residential blocks. A single leaking joint is often how a building in Stratford St Mary first comes to us: we look at the rest while we are there and tell you what we find.

For buildings around smaller places like Stratford St Mary, we group work so one trip covers it. Send photos of the frames and joints and we’ll give a fixed quote.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we are clear about what is covered before work starts.

Keeping the joints sound

To get the most from the new sealant:

  • List the paperwork your organisation requires when you send details
  • Make mastic part of routine maintenance checks
  • Track which buildings were done and when
  • Make it easy for occupiers to report draughts

Protect entrance and corridor joints from knocks where possible. Knocks cause many early failures in communal areas.

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

Frames, entrances and external joints in Stratford St Mary

Rainfall across the South East, Stratford St Mary included, is lower than in many parts of the UK. Outside work still depends on dry joints, while the elevations that take the most sun tend to show hardened mastic first. Central London is about 56 miles from Stratford St Mary. 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.

Buildings close to stations like Manningtree station (to the south-east of Stratford St Mary) are often flats over shops, with frame mastic to keep sound. If your remit includes a building such as Stratford St Mary Primary School, frame and door mastic can be programmed for the holidays. For owners of several units at places like Langham Barns Business Centre, which lies south-west of Stratford St Mary, one programme can deal with frame and external mastic across the lot.

Yes, and several blocks can go on one quote. Give us the building’s details and say how residents are notified, and we’ll quote and plan to suit.

What if the old mastic contains asbestos?

What paperwork can you provide?

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 are CHAS accredited and a Constructionline member.

Do you do block-wide mastic programmes?

Yes, planned programmes suit estates and portfolios. The quote can be split however suits your budgeting.

Do you guarantee the mastic work?

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

When can the area be used after sealing?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we’ll confirm the curing time on the day.

What sets the cost

Quotes vary with the job. It mainly depends on:

  • Distance, for remote addresses
  • Specialist products, such as fire-rated or hygienic sealants
  • Removal of failed or old sealant
  • Joint width, depth and condition

We don’t publish prices, since every building and every scope is different. Call for a quote.

What to include in your enquiry

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • The asbestos register, for older buildings
  • The type of building and who uses it
  • A wide shot and a close-up of the area
  • Approximate linear metres or a joint schedule

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

When it isn’t the sealant

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

  • Leaks from above rather than through a joint
  • Broken glass or failed sealed units
  • Frames that are rotten, warped or broken

If you are not sure, just give us a call on 01277 525 020 or email the details over and we’ll give you a straight answer.

Surfaces we seal

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

Owners, agents and contractors

If you look after buildings for someone else, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

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

Why act early in Stratford St Mary

Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. Halls, stores and units around places like Stratford St Mary may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why appoint us

  • Work to your specification and the manufacturer’s guidance
  • RAL and finish matching where the product range allows
  • One contact handling all your sites
