Mastic sealing near Great Bentley

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

General trades versus a specialist

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

About our mastic sealing in Great Bentley

For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on shopfronts below residential blocks, communal entrances and stairwells and external wall and movement joints, and the usual reasons a site gets in touch are worn sealant at communal door frames and open joints in brickwork or panels. Whoever orders the work in Great Bentley, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.

Converted and older buildings in and around Great Bentley often put modern windows into old walls. Perimeter joints need a sealant that suits both frame and masonry.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

From enquiry to sign-off

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 neighbouring businesses or buildings around Great Bentley need work too, visits can be combined. Tell us your site hours and we’ll plan around them.

  1. A building-by-building inspection lists the failed joints.
  2. You get a fixed quote, per block or for the whole programme.
  3. Dates and areas are agreed so occupiers can be told.
  4. Old mastic is removed and the joint faces prepared.
  5. Joints are resealed and tooled.
  6. Each building is checked and signed off with the 12-month guarantee.

Getting the site ready

Planned mastic for Great Bentley portfolios

Great Bentley lies roughly 56 miles out from central London. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Rainfall across the South East, Great Bentley included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and elevations facing the sun and the prevailing weather are typically where frame mastic ages first.

Buildings close to stations like Great Bentley station, less than half a mile to the south of Great Bentley, are often flats over shops, with frame mastic to keep sound. With historic buildings such as Thorpe Hall (to the east of Great Bentley) in the wider area, owners of older properties around Great Bentley should expect mastic to need a product that suits old masonry.

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.

Tenement and older buildings

Traditional buildings have joints that need a careful approach. The material either side of the joint shapes the product choice.

Why it’s worth doing now in Great Bentley

A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. For buildings in places like Great Bentley, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.

Pricing mastic joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

Your questions answered

Is Great Bentley too small for you to travel to?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Will you take on work at estates like Plough Road Business Centre, close to Great Bentley?

Yes. We cover Great Bentley and the area around it, including industrial estates, business parks and retail parks such as Plough Road Business Centre. To start, just phone 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

Will residents or tenants be disturbed?

Occupiers stay in the building throughout. We flag any areas that need internal access well before the dates so it can be arranged.

Do you need to see the site first?

Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit before quoting.

When can the area be used after sealing?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

How much does the work cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.

Can you plan resealing across several buildings?

Yes. We survey and price each building, then work through them in order, and the programme can start with the worst.

Honest limits

We check first that sealant really is the fix. It won’t put right:

  • Frames that are rotten, warped or broken
  • Leaks from above rather than through a joint
  • Misted or failed double-glazed units

Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Signs you need mastic sealing in Great Bentley

Sunlight and weather break mastic down over time. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.

If one of these sounds familiar, it’s time for a closer look:

  • Occupiers reporting cold air round windows
  • Mastic failing across several blocks on an estate
  • Communal area joints that look neglected
  • Leaks at window and door perimeters

If you’re responsible for a building such as Church of St Mary, frame and door mastic needs the same attention as any other property.

What your quote should include

  • Their public liability cover
  • Whether old or failed sealant will be cut out, not overlaid
  • Will RAMS and insurance details be available?
  • Is the sealant right for the movement and the substrate?
