What does a balcony or terrace in Redditch need?
Balconies in Redditch 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.
Redditch's flat roofs are mostly on shops with flat-roofed rear stores below flats, with plenty on lock-up garage blocks on estates too. England averages roughly 870 mm of rain a year and the West Midlands sits close to that, so falls and outlets are the difference between a roof that drains and one that ponds.
How much does balcony or terrace waterproofing cost in Redditch?
At West Midlands guide rates, a 12 m² balcony in a liquid-applied system including scaffold comes to £1,900–£3,250 including VAT. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Balcony (12 m²), liquid-applied, scaffold | £1,900–£3,250 |
| Single garage (18 m²), EPDM rubber | £1,600–£2,800 |
| Extension (20 m²), GRP, new deck + insulation | £3,000–£5,400 |
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?
- Sealed details at doors, outlets, walls and balustrade posts
- Written workmanship guarantee, with approvals handled where needed
- Free survey of the deck, falls, outlets and door thresholds
- Lifting and setting aside of existing paving or decking
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 Redditch?
£1,900–£3,250 for a 12 m² balcony in a liquid-applied system including scaffold, at West Midlands guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
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.
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.
