Mastic sealing in Rettendon

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

After the work

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Log resealing dates block by block
  • List the paperwork your organisation requires when you send details
  • Share the asbestos register when you send details
  • Include mastic in your cyclical inspections

Log the date and extent of the resealing for each block. It helps plan the next round and shows what was done.

One failed perimeter typically means others on the same building are close, so it pays to look at the whole elevation. Doing them together saves going back again and again.

How we handle mastic sealing in Rettendon

We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. We work on communal entrances and stairwells, external wall and movement joints and balcony and threshold joints, and the failures we’re asked to look at most are occupiers reporting cold air round windows and patchy repairs in mismatched sealant. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Rettendon, preparation and product choice get the time they need.

In and around smaller places like Rettendon, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Mastic around frames and on external joints wears out in time, whatever the building.

Every job we finish is backed by a 12-month workmanship guarantee, in Rettendon as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the quote is worked out

Before we quote, we look at:

  • How accessible the joints are
  • How much existing material needs removing
  • Joint width, depth and condition
  • Which sealant the job calls for

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

Details that help us quote

For an accurate fixed quote, we need to understand the site. Send us:

  • Photos of the joints, close up and from further back
  • How the joints are reached, and at what height
  • Any dates the work must fit around
  • What the building is and how it’s used

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Common problems we fix in Rettendon

UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear most of all on the sunniest and most exposed elevations.

What tends to prompt an enquiry:

  • Movement joints with sealant missing
  • Brittle perimeter mastic across a building
  • Old repairs sealed over failed mastic
  • Communal area joints that look neglected

If you look after a block within reach of Battlesbridge station (2.2 miles south of Rettendon), frame and balcony mastic can be renewed on one programme.

Comparing quotes

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Proof of insurance
  • How they’ll work around occupants
  • What site paperwork they can supply

Questions to ask before you appoint anyone

When it isn’t the sealant

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Masonry that has broken away beside the joint
  • Water coming in from the roof or rainwater goods
  • Broken glass or failed sealed units

If you’re not sure, just phone 01277 525 020 or send photos by email and we will give you a straight answer.

Where we work in Rettendon

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

Our process

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in 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. For a building around Rettendon, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. We send a fixed quote that sets out the joints, the products and the programme.
  3. The sequence and the dates are fixed with you, giving you what you need to notify occupiers.
  4. Failed mastic is removed and the faces taken back to sound, dry material.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Flag any permit to work we will need
  • Point out any areas we must not close
  • For older buildings, check the asbestos register before work

Should maintenance staff do it?

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

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.

Rettendon: questions and answers

Is Rettendon too small for you to travel to?

Not at all. Rettendon is within our area. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Will you take on a block within reach of Battlesbridge station?

Yes. Blocks of any size are within what we do. We work to your notice and access arrangements.

How do you reach windows on upper floors?

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

Can you work to our specification?

Yes. Send it with your enquiry, and we’ll price the work to it.

How long does a typical visit take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

What paperwork can you provide?

We are CHAS accredited, a Constructionline member and carry public liability insurance. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Will you just go over the old sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.
