What does a balcony or terrace in Maesteg need?

Balconies in Maesteg are often re-waterproofed when the ceiling below starts to stain. On many older balconies, the membrane was laid under tiles or screed with no way to inspect it, so by the time the leak appears, water may have been tracking under the surface for a long time.

In a town like Maesteg, flat roofs are commonly found on 1930s semis with flat-roofed garages and kitchen extensions or newer estates where the first extension roofs are now being replaced. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof.

How much does balcony or terrace waterproofing cost in Maesteg?

At Wales guide rates, a 12 m² balcony in a liquid-applied system including scaffold comes to £1,750–£3,000 including VAT. The fixed price comes after a free survey for new and replacement roofs.

JobGuide price inc VAT
Balcony (12 m²), liquid-applied, scaffold£1,750–£3,000
Single garage (18 m²), EPDM rubber£1,450–£2,600
Extension (20 m²), GRP, new deck + insulation£2,750–£4,950

How long does it take to waterproof a balcony?

A small balcony is typically waterproofed in two to four working days, plus time for scaffold if it is above ground floor. Liquid and GRP systems need dry weather and cure time between coats, which sets the pace.

The balcony door will be out of use while the membrane is laid and curing, and the room behind may be noisy while old paving or screed is broken out. If the team needs to work through the house, we agree a route and protect floors. Larger terraces with paving or decking take longer, because the finish has to be lifted and reinstated. Resin systems smell while they cure, so nearby windows are best kept closed.

What's included?

  • Sealed details at doors, outlets, walls and balustrade posts
  • Free survey of the deck, falls, outlets and door thresholds
  • Strip-out of the failed membrane and deck repairs
  • New liquid, GRP, single-ply or asphalt waterproofing

Building regulations in Wales

The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.

How much does balcony or terrace waterproofing cost in Maesteg?

£1,750–£3,000 for a 12 m² balcony in a liquid-applied system including scaffold, at Wales guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

Is a roof terrace heavier than a normal flat roof?

Yes. Paving, people, planters and furniture all add load, so a structural engineer should confirm the roof can carry it before a terrace is formed.

How long does balcony waterproofing last?

It depends on the system and how well it is protected. As indicative ranges, liquid-applied systems last 10–25+ years by product and mastic asphalt 30–60, with good maintenance.
