Need mastic sealing in Kelvedon Hatch?

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

Mastic sealing in Kelvedon Hatch

We diagnose before we prescribe: which joints have failed, why, and whether sealant is the right answer. Old mastic is removed entirely, the faces prepared, primer used where the maker specifies it and new sealant tooled in and backing rod used wherever a joint is deep. The enquiries we see most involve no planned programme for sealant and a mix of products and colours from past repairs, across shopfronts below residential blocks, external wall and movement joints and window and door perimeters on blocks. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Kelvedon Hatch, preparation and product choice get the time they need.

For buildings around smaller places like Kelvedon Hatch, we group work so one trip covers it. Photos of each elevation help us quote accurately.

A 12-month guarantee applies to all our work. Should something we installed fail, phone 01277 525 020 or email the details over and we will come back to it.

Cost factors for mastic joints

What shapes the price:

  • Backing rod, priming and other preparation
  • Specialist products, such as fire-rated or hygienic sealants
  • Whether old sealant has to be cut out first
  • Site requirements such as inductions and permits

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Details that help us quote

It doesn’t need to be a full survey. These details are enough to start:

  • Any dates the work must fit around
  • The type of building and who uses it
  • Whether an asbestos survey exists
  • Approximate linear metres or a joint schedule

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call 01277 525 020 or email the details over if you’d rather talk the job through.

Kelvedon Hatch: questions and answers

Is Kelvedon Hatch off your patch?

No. Places such as Kelvedon Hatch are covered as much as the big towns. We work across Greater London and the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Is Hallsford Bridge Industrial Estate, near Kelvedon Hatch, within your area?

Yes. Estates, retail parks and business parks around Kelvedon Hatch, Hallsford Bridge Industrial Estate among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Can you take on resealing for a block portfolio?

Yes, block and estate work is a core part of what we do. We work through buildings in a planned order so you can plan around it.

How long does a typical visit take?

The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Can you plan resealing across several buildings?

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

How much does the work cost?

Each job is quoted on its own details. For yours, call the office on 01277 525 020 or send photos by email.

When to call us in Kelvedon Hatch

Frames, panels and masonry expand and contract through the year, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope long before it should.

Common reasons buildings call us in:

  • Patchy repairs in mismatched sealant
  • Cracked, hardened mastic round windows on a block
  • No planned programme for sealant
  • Leaks at window and door perimeters

With historic buildings such as Ingatestone Hall, 5 miles east of Kelvedon Hatch, in the wider area, owners of older properties around Kelvedon Hatch should expect mastic to need a product that suits old masonry.

What your quote should include

  • How they’ll work around occupants
  • What the guarantee covers, and for how long
  • Their pre-qualification and accreditations
  • Their public liability cover

How to choose a sealant contractor

What sealant work can’t fix

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Materials that need asbestos testing before work
  • Cracked or crumbling render, brick or stone at the joint edges (we will tell you if so)
  • Frames that are rotten, warped or broken

If you’re not sure, just call 01277 525 020 or send photos by email and we’ll give you a straight answer before you book.

Surfaces we seal

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

After the work

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Track which buildings were done and when
  • Look at the sunniest and most exposed elevations first
  • Make mastic part of routine maintenance checks
  • List the paperwork your organisation requires when you send details

Keep records of when each building was resealed. That makes future programmes easier to plan and shows what was done.

Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.

For owners and agents in Kelvedon Hatch

Kelvedon Hatch lies roughly 20 miles out from central London. Managed blocks of flats are a big part of commuter-belt property; their frame mastic often ages block-wide. Rainfall across the South East, Kelvedon Hatch included, is lower than in many parts of the UK. Even so, frame mastic only goes on in dry, workable conditions, and the sunniest, most exposed sides of a building normally need attention first.

If your remit includes a building such as Kelvedon Hatch Community Primary School, frame and door mastic can be programmed for the holidays. Trustees of buildings like New Church of St Nicholas can bring frame and external mastic into a planned maintenance list.

Related advice

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
