Mastic sealing in Woolbridge, done properly

On a residential block, the work happens around people’s lives. The sequence, the areas and the dates are settled with you, giving you what you need to notify residents. Entrances and stairwells are kept in use while we work. If you have a mix of products and colours from past repairs and communal area joints that look neglected, we can put it right, whatever the surface. For commercial sealant work in Woolbridge, you deal with one contact from quote to sign-off, whether it’s one building or several.

In and around smaller places like Woolbridge, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.

Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

General trades versus a specialist

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.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What we’re called out for in Woolbridge

UV and rain age external sealant. It stiffens, stops stretching and cracks most of all on the sunniest and most exposed elevations.

Look out for the following:

  • Estate-wide sealant that is simply worn out
  • Damaged joints in communal entrances and corridors
  • Brittle perimeter mastic across a building
  • Patchy repairs in mismatched sealant

For owners of several units at places like Millbrook Industrial Estate, which lies north-west of Woolbridge, one programme can deal with frame and external mastic across the lot.

What your quote should include

  • Whether their applicators hold CSCS cards
  • What the guarantee covers, and for how long
  • What level of public liability insurance do they hold?
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

What we can’t put right

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

  • Cracked or crumbling render, brick or stone at the joint edges (we’ll tell you if so)
  • Frames that are rotten, warped or broken
  • Roof leaks, gutters or failed flashings that aren’t sealant joints

If you are not sure, just give us a call on 01277 525 020 or use the quote form and we will give you a straight answer before you book.

Joints and surfaces we work on

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

Common questions from Woolbridge clients

We manage a building near Crowborough station. Can you help?

Yes, we work for agents, landlords and housing associations with blocks of every size. We work to your notice and access arrangements.

Do you cover business parks and estates near Woolbridge, such as Millbrook Industrial Estate?

Yes. Estates, retail parks and business parks around Woolbridge, Millbrook 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 weather delay the job?

It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

What if the old mastic contains asbestos?

We don’t remove asbestos-containing materials. Anything suspect is tested before we carry on, and the duty to manage asbestos sits with the dutyholder.

Can people stay in the building while you reseal?

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

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

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.

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Track which buildings were done and when
  • Start inspections with the most exposed faces
  • Share the asbestos register when you send details
  • Encourage occupiers to report problems at frames

Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.

Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.

Mastic sealing in Woolbridge: the local picture

At about 36 miles from central London, Woolbridge is within reach of the capital. Commuter-belt towns tend to have plenty of managed blocks near stations and town centres; their frame mastic often ages block-wide. Woolbridge sits in one of the drier corners of the country, the South East. Outside work still depends on dry joints, and the sunniest, most exposed sides of a building typically need attention first.

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

Surface by surface

Communal areas

We keep entrances and stairs open throughout. Work is planned in sections.

External movement joints

Movement joints are cleaned out, backed with rod and resealed with a sealant of the right movement class.

Our process

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For work around Woolbridge, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  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. Buildings are completed in turn.

Preparing the site

  • Send any specification or drawings in advance
  • Tell us your opening times and when work is allowed
  • Agree which areas must stay open
