Balconies and roof terraces in Blaydon-on-Tyne

A leak under a balcony in Blaydon-on-Tyne usually shows up as a stain on the ceiling below, but the cause is often at the door threshold or an outlet. We trace it at survey, then waterproof the whole balcony properly rather than sealing one spot and hoping for the best.

What does a balcony or terrace in Blaydon-on-Tyne need?

A roof terrace in Blaydon-on-Tyne may be re-waterproofed when the owners want to change the finish, swapping old tiles for decking or porcelain on pedestals. Lifting the surface exposes the membrane, and replacing it then avoids having to lift the new finish again later.

In a town like Blaydon-on-Tyne, flat roofs are commonly found on bungalows with flat-roofed side extensions and dormers or lock-up garage blocks on estates. England averages roughly 870 mm of rain a year; the North East is drier than the west but cold and windy near the coast, so wind uplift and freeze-thaw are in the specification.

Which waterproofing system is best for a balcony?

For most small balconies, a liquid-applied membrane is the practical choice, because it is brushed or rolled on and forms one continuous layer around posts, door frames and outlets with no seams to fail. Many systems include a hard-wearing, anti-slip topcoat.

GRP fibreglass gives a rigid, walkable surface and suits balconies left exposed rather than paved. On larger roof terraces under paving or decking, single-ply membranes are common, and mastic asphalt has a long record on concrete terraces and blocks of flats.

The choice also depends on what goes on top. Paving on pedestals protects the membrane, while an exposed balcony needs a system rated for foot traffic in its own right. We specify the build-up at survey.

What's included?

  • Written workmanship guarantee, with approvals handled where needed
  • Sealed details at doors, outlets, walls and balustrade posts
  • New liquid, GRP, single-ply or asphalt waterproofing
  • Free survey of the deck, falls, outlets and door thresholds

Building regulations in England

Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.

How much does balcony or terrace waterproofing cost in Blaydon-on-Tyne?

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

Why is water coming through the ceiling below my balcony?

The usual causes are a failed door threshold, a blocked or poorly sealed outlet, or a fixing through the membrane. A survey, sometimes lifting paving, finds the source.

Do you install balustrades?

Our work is the waterproofing and drainage. We detail the membrane around balustrade fixings so they stay watertight, and we can advise on where posts should be fixed.
