Common problems we fix in Harbridge

Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant and the repair soon fails.

Look out for the following:

  • Damaged joints in communal entrances and corridors
  • A mix of products and colours from past repairs
  • Estate-wide sealant that is simply worn out
  • Occupiers reporting cold air round windows

Churches, halls and community buildings such as Church of All Saints are looked after by trustees and committees like any other owner, and their frames, doors and external joints need mastic renewed in time.

Questions to ask before you book

  • Who will actually carry out the work
  • Can the work be phased to keep areas open?
  • Health and safety accreditation such as CHAS
  • Whether old or failed sealant will be cut out, not overlaid

Our contractor checklist

Mastic sealing in Harbridge

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, with backing rod setting the depth where it’s needed. Most enquiries involve movement joints with sealant missing and mastic failing across several blocks on an estate, on communal kitchens and washrooms, balcony and threshold joints and communal entrances and stairwells. One point of contact handles commercial sealant work in Harbridge from the first photographs to the final walk-round, whether it’s one building or several.

Rural conversions near places like Harbridge often set modern frames into older stone, flint or brick. The mastic needs to suit an irregular masonry face and the look of the building.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

How the quote is worked out

We price every job individually. The main factors are:

  • How much existing material needs removing
  • Induction, permit and paperwork requirements
  • The total length or number of joints
  • Phasing around occupants

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Before you send an enquiry

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

  • Rough lengths or quantities, or drawings if you have them
  • Your programme or deadline
  • Access details, including height
  • A wide shot and a close-up of the area

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call the office on 01277 525 020 or email the details over if you’d rather talk the job through.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Planned mastic for Harbridge portfolios

Harbridge is in the South East, one of the UK’s drier regions. External mastic still waits for dry faces and the right temperature, and south- and west-facing elevations, which take the most sun and rain, often age first.

If you own or manage units on a site such as Headlands Business Park (2.2 miles south of Harbridge), failed mastic on frames, door surrounds and external joints can be dealt with unit by unit.

Harbridge is about 3 miles north of Ringwood, in Hampshire. Businesses, contractors and managing agents in Harbridge can call on us for mastic joints, as part of our coverage of Hampshire. Harbridge is one of 723 places we cover in Hampshire for mastic joints. For work in that direction, see our Southampton page (18 miles or so).

Work on mastic joints is covered throughout BH24, for business premises of every kind. If your site is on Kent Lane and Churchfield Lane or close by, we can quote for mastic joints. Close to Harbridge, our area also takes in Ibsley (1 mile south-east), Mockbeggar (1 mile east), Ellingham (1 mile south), South Gorley (1 mile east) and Rockford (2 miles south-east).

Common questions from Harbridge clients

Is Harbridge too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.

Do you take on block-wide or estate-wide mastic work in Harbridge?

Yes. Portfolio-wide programmes are a regular request. Residents are given notice through you, and the work moves building by building.

Can you seal joints high up on a block?

Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.

Can you take on resealing for a block portfolio?

Yes, that’s exactly who this service is for. We work through buildings in a planned order so you can plan around it.

Is asbestos a concern with old mastic?

In older buildings, old mastic can contain asbestos. We ask for the asbestos register or survey before work starts, and if it’s suspected, work stops until it’s tested.

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 weather delay the job?

It can, for external work. 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. Internal work is far less affected.

When it isn’t the sealant

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Misted or failed double-glazed units
  • Leaks through the frame itself rather than the perimeter
  • Leaks from above rather than through a joint

If in doubt, give us a call on 01277 525 020 or email us and we will say what we think before you book.

Why deal with it now?

A bead run over old mastic can look like a repair. It won’t grip the old sealant and soon comes away. Cutting out and resealing properly does it once. Converted and older buildings near places like Harbridge tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.
