Mastic sealing in Bicknacre

For blocks and buildings in Bicknacre and across Essex, the process is the same: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote, and site visits can be arranged. We work on shopfronts below residential blocks, balcony and threshold joints and communal kitchens and washrooms, and what we are called in for most is communal area joints that look neglected and leaks at window and door perimeters. A single leaking joint is often how a building in Bicknacre first comes to us: we look at the rest while we are there and tell you what we find.

Rural conversions near places like Bicknacre often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

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.

Why act early in Bicknacre

Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work with less control over timing. Older rural buildings around Bicknacre move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

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.

Why us?

  • Colour agreed before work starts
  • Matching to RAL references, product permitting
  • Health and safety: CHAS accredited
  • 12 months’ guarantee on every job

Your questions answered

Will you take on a block within reach of South Woodham Ferrers station?

Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.

Is Bicknacre too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Is mastic sealing guaranteed?

Every building we reseal has a 12-month guarantee. It covers our workmanship, not later building movement, damage or frame failures.

Who decides which product is used?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Can you seal joints high up on a block?

It depends on the building. We agree access with you at quote stage so there are no surprises.

How long does a typical visit take?

That varies with the scale of the job, but the work typically takes anything from a day to a few weeks, depending on the number of buildings and joints. For bigger or phased jobs, we’ll set out a timescale with the quote.

Do you do block-wide mastic programmes?

Block-wide and estate programmes are common. You get a fixed quote per building or for the whole job.

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. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

What sets the cost

What shapes the price:

  • How much existing material needs removing
  • Distance, for remote addresses
  • How much there is to seal
  • Working within restricted access windows

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Before you send an enquiry

There’s no need for a formal survey. These details are enough to start:

  • Whether an asbestos survey exists
  • Specification clauses that apply
  • Clear photos of the problem areas
  • The site address and postcode

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, give us a call on 01277 525 020 or email a schedule or drawings.

From enquiry to sign-off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes a few days for most blocks, with larger programmes scheduled building by building, and our waste is bagged and taken away as we go. Smaller jobs around Bicknacre can be grouped with others nearby. You’ll have a fixed quote before work starts.

  1. First comes a look at the joints and, for older buildings, the asbestos records.
  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. We finish each building before moving to the next.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Send any specification or drawings in advance
  • Agree which areas must stay open

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Maintenance after handover

For the best life from the joints:

  • Share your contractor requirements early
  • Reduce knocks to communal area joints
  • Make it easy for occupiers to report draughts
  • Log resealing dates block by block

Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away and record where they are.

Joints on a building age together, so it pays to look at the whole elevation. Doing them together saves going back again and again.

What sealant work can’t fix

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

  • Leaks through the frame itself rather than the perimeter
  • Masonry that has broken away beside the joint
  • Leaks from above rather than through a joint

Not sure which it is? You can phone 01277 525 020 or email the details over and we will tell you honestly before you book.

What we seal

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

For owners and agents in Bicknacre

At about 32 miles from central London, Bicknacre is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres. Rainfall across the South East, Bicknacre included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, while the elevations that take the most sun tend to show hardened mastic first.

If you look after a block within reach of South Woodham Ferrers station, 3.1 miles south of Bicknacre, frame and balcony mastic can be renewed on one programme. With historic buildings such as Danbury Place, 2 miles to the north-west of Bicknacre, in the wider area, owners of older properties around Bicknacre should expect mastic to need a product that suits old masonry. Schools and community buildings such as Priory Primary School need frame and external mastic kept sound like any building.
