Decking in Thornaby
Decking across Thornaby, TS17: composite £120 to £180 per square metre, timber £80 to £120, repairs £300 to £2,000. Level post-war gardens with side access make this some of the most straightforward and predictably priced decking work on Teesside.
Straightforward gardens, predictable prices
Thornaby's housing is mostly interwar and post-war, and around Mandale, Harold Wilson Drive and the streets off Thornaby Road the gardens are square, close to level and have side or rear access. That is the easiest combination decking gets, and it shows in the quotes: fewer unknowns, less labour hauling materials, and a straight board run rather than complicated levels. A 20m² deck off the back door is the classic local job, £1,700 to £2,400 in softwood or £2,600 to £3,500 in composite, in two to three days on site.
Replacing tired 2000s decking
Thornaby has plenty of decks put down in the decking boom of the early 2000s, and they are now at the age where they either need refurbishing or replacing. The test is quick: a screwdriver into the boards and into the joists. Soft boards on a solid frame is a £300 to £700 refresh with new boards, sanding and oil. Soft joists means the frame is going, and money spent patching it is money lost, because these decks were nearly always built straight onto the soil with no tape and no ventilation gap. That is covered on the repair and refurbishment page.
Decking over an existing patio
Many Thornaby gardens already have a concrete or slab patio from decades ago, cracked, sloping the wrong way, or simply grim. Decking over it is often the cheapest route to a level, dry, usable space, and a sound base helps: the frame gets packed and shimmed level and a ventilation gap kept around the whole perimeter so water is not trapped. Where the paving is loose, hollow or bedded on nothing, it comes out first, and that appears as its own line on the quote rather than a surprise on day two.
Getting a Thornaby garden priced
Because the plots are simple, the quote turns mainly on area, material, and whether there is a step or two at the door. Have the rough dimensions and the threshold height ready. Full figures are in the 2026 cost guide, and the material choice is set out on the composite and timber pages.
