Mastic sealing for businesses in Maldon

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

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. In a town such as Maldon, most jobs are single buildings. Your photos, drawings or a site visit come first, followed by a fixed quote.

  1. Each block or building is walked and the failed joints recorded with the likely cause.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. Old sealant is stripped and each face prepared back to firm material.
  5. Backing rod and primer go in as the joint requires, then the new bead is placed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Tell us your opening times and when work is allowed
  • Let us know about inductions and permits
  • Arrange parking or a loading space

How we handle mastic sealing in Maldon

Our clients include managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios. Many prefer a planned programme to one-off visits, with each block quoted and scheduled in turn. The enquiries we see most involve worn sealant at communal door frames and leaks at window and door perimeters, on external wall and movement joints, communal kitchens and washrooms and balcony and threshold joints. Whoever orders the work in Maldon, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

In a town such as Maldon, buildings managed by agents and landlords range from flats over shops to small blocks and offices. Window and door perimeters, external joints and communal areas all need their mastic renewed from time to time.

A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Maintenance after handover

After handover, these steps help:

  • List the paperwork your organisation requires when you send details
  • Plan resealing building by building rather than complaint by complaint
  • Keep a record of when each building was resealed
  • Make it easy for occupiers to report draughts

Encourage occupiers to report water or draughts at frames. A quick report keeps a small repair small.

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

Doing it in-house

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.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Block-wide mastic in Maldon

The sea is no more than about 1 mile from Maldon. Sea-facing elevations take driven rain and salt, and their mastic shows it before the sheltered sides do, and they deserve more regular inspection. Rainfall across the South East, Maldon included, is lower than in many parts of the UK. Outside mastic still needs a dry joint and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.

If you are responsible for a building such as Church of St Mary, frame and door mastic needs the same attention as any other property. For a school such as Maldon Primary School, perimeter mastic on windows and doors is a holiday job.

FAQs: Maldon

Our building in Maldon is near the coast: does that change the sealant?

It can. Coastal exposure works external joints harder than inland weather. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Will you take on work at estates like Riverside Industrial Estate, close to Maldon?

Yes. Our area takes in Maldon and its surroundings, with estates and business parks such as Riverside Industrial Estate included. Photos and a short description are enough for a first look.

Do you work for managing agents and housing associations?

Yes, that’s exactly who this service is for. We work through buildings in a planned order with dates agreed in advance.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Can you seal joints high up on a block?

Every block is different. We agree access with you at quote stage so there are no surprises.

Is asbestos a concern with old mastic?

In older buildings, old mastic can contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.

Will you quote for a small job?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

When to call us in Maldon

Previous repairs often sealed new mastic over old. New silicone has nothing to grip on old silicone, so these repairs rarely last.

Typical triggers for a call:

  • Leaks at window and door perimeters
  • Repeated reactive repairs to the same buildings
  • Estate-wide sealant that is simply worn out
  • Draught complaints from residents or tenants

Property owners at sites such as Riverside Industrial Estate, 0.5 miles north of Maldon, can have mastic renewed between lettings.

Before you book anyone

  • The terms of the workmanship guarantee
  • What site paperwork they can supply
  • Health and safety accreditation such as CHAS
  • Is the sealant right for the movement and the substrate?

Priority order can follow condition, complaints or your maintenance plan. You get one fixed quote per building or for the whole estate.

Tenement and older buildings

Some old mastics in pre-2000 buildings contain asbestos, so we check the asbestos register or survey first. If it’s suspected, work stops until it’s tested.
