Mastic sealing for Roughdown sites

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

How the job changes by surface

Commercial and mixed-use buildings

Landlords with commercial portfolios have shopfronts, office entrances and external joints to look after. We work across portfolios on a planned basis.

Estate-wide resealing programmes

A programme can start with the worst buildings and work down. Quotes can be per block or for the full programme.

How we handle mastic sealing in Roughdown

In buildings from before 2000, some old mastics contain asbestos. Before we disturb it, we ask to see the asbestos register or survey and if it’s suspected, work stops until it’s tested. Removing asbestos-containing material isn’t something we do. We work on window and door perimeters on blocks, communal kitchens and washrooms and shopfronts below residential blocks, and the failures we’re asked to look at most are movement joints with sealant missing and communal area joints that look neglected. A single leaking joint is often how a building in Roughdown first comes to us: we look at the rest while we’re there and tell you what we find.

Around smaller places like Roughdown, older walls fitted with newer windows are a familiar sight. The mastic needs to suit an irregular masonry face and the look of the building.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

When to call us in Roughdown

In communal areas, joints take knocks from bins, bikes, buggies and deliveries, and low-level joints get damaged. Regular cleaning wears them further.

Site and facilities staff are often the first to spot these:

  • A mix of products and colours from past repairs
  • Occupiers reporting cold air round windows
  • Cracked, hardened mastic round windows on a block
  • Open joints in brickwork or panels

Landlords with units on estates such as Glenmore Business Park, 1.4 miles to the north of Roughdown, can bring frame, door and external mastic across several units into one programme.

What your quote should include

  • Are they CHAS accredited or on Constructionline?
  • Will failed sealant be removed rather than covered?
  • The terms of the workmanship guarantee
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

Site staff or a sealant specialist?

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Your questions answered

Do you work for managing agents with blocks near Netley station?

Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.

Is a smaller place like Roughdown outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you do block-wide mastic programmes?

Yes. We survey and price each building, then work through them in order starting wherever is most urgent.

Can weather delay the job?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Do you work for managing agents and housing associations?

Yes, that’s exactly who this service is for. Buildings are scheduled in turn so you can plan around it.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

How many days will you need on site?

It depends on the scope, but the work typically takes a few days for most blocks, with larger programmes scheduled building by building. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

For managing agents and facilities managers

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Mastic sealing in Roughdown: the local picture

Roughdown lies within about 2 miles of the sea. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints. Roughdown sits in one of the drier corners of the country, the South East. 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.

Buildings close to stations like Netley station, 4.3 miles to the north-east of Roughdown, are often flats over shops, with frame mastic to keep sound. If your remit includes a building such as Blackfield Primary School, frame and door mastic can be programmed for the holidays.

Roughdown is about 3 miles south of Hythe, in Hampshire. Anywhere in SO45, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. 723 places across Hampshire fall within our area, Roughdown among them. We also cover Southampton, some 7 miles away.

We take on mastic joints across the SO45 postcode area, whatever the building. If your building is just outside Roughdown, we cover Holbury (1 mile north), Blackfield (1 mile east), Little Holbury (1 mile north), Langley (1 mile south-east) and Hardley (1 mile north). Nearby towns on our patch include Gosport (10 miles east), Eastleigh (10 miles north), Fareham (9 miles east), Totton (9 miles north-west), Chandler's Ford (11 miles north) and Hedge End (8 miles north-east).

Leave it or put it right?

Open external joints let water into walls and around frames. That can lead to damp, staining and damage to finishes, which is harder to deal with than resealing. For buildings around smaller places like Roughdown, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Why us?

  • Fully insured, including public liability cover
  • Joints cleaned back to sound surfaces
  • A fixed quote before work starts
  • Colours chosen to suit frames, cladding or finishes where possible
