Service Overview

Garden Renovations —
The Brief, In Plain English.

What It Is

Garden renovations covers all hard landscaping — patios in porcelain, sandstone or block paving; retaining and boundary walls; steps; drainage; sleeper edges; outdoor kitchens; turfed and planted areas finished around the hard build. We handle the structural side that gardeners typically don't.

Who It's For

Homeowners refreshing a tired or unusable garden; sellers boosting kerb appeal before listing; landlords improving outdoor space for rental appeal; clients who've been quoted by gardeners and want the structural build done properly.

When You Need It

Spring through autumn for the bulk of patio and walling work. Drainage and retaining wall work can run year-round with the right ground conditions. Plan 4–8 weeks ahead — good slab and bedding aggregate runs out fast in summer.

Why It Matters

Most failed patios are failed sub-bases — not failed slabs. Skimp on the dig depth, the MOT compaction or the drainage and the surface fails inside two winters. We dig deep, compact properly, fall the surface to drains, and finish to a line.

What Happens If You Wait

The Cost Of
Doing Nothing.

A bad patio doesn't just look bad — it pushes water at your house.

Risks Of Ignoring It

  • Patio falling toward the building instead of away — damp at DPC, internal damage.
  • Sunken slabs from inadequate sub-base — tripping hazard, liability, full lift-and-relay.
  • Retaining wall failure — material loss, fence collapse, neighbour disputes.
  • Drainage tied into surface water without permission — utilities can charge to disconnect.
  • Frost-heave on poorly-jointed slabs — full strip and rejoint.

Common Mistakes Customers Make

  • ×Laying onto soil with a sand bedding 'because the gardener said so'.
  • ×Mortar joints over un-flexed sub-base — every joint cracks.
  • ×Wrong slab spec for vehicle access — block paving over slabs that need machine laying.
  • ×No drainage plan — water pooling at the back of the patio.

Our Process

First Call To
Final Sign-Off.

01

Site Survey

Measure, check levels, identify drainage routes, confirm slab spec and any structural elements (walls, steps, retaining).

02

Fixed Quote & Plan

Itemised quote with slab spec, sub-base depth, drainage detail, walling and finishes — no vague day-rate gardening prices.

03

Dig & Sub-Base

Excavate to depth, dispose of spoil, install Type 1 MOT in compacted layers — the bit nobody sees that decides the lifespan.

04

Lay & Build

Slabs laid on a full mortar bed, walls built to spec, drainage installed and connected, falls checked across the area.

05

Joint & Finish

Joints filled with the right resin or mortar, sealed where specified, area cleaned, snag walked together.

Why It's Worth It

What You
Actually Get.

Sub-Base Done Properly

Type 1 MOT excavated and compacted to depth — the difference between a patio that lasts 5 years and one that lasts 25.

Falls Engineered

Surface falls calculated to push water to drains, away from the building. Checked with a level, not a guess.

Drainage Designed In

ACO channels, soakaways, gully connections — water has somewhere to go before we lay a single slab.

Structural Walls, Not Stacked Stone

Retaining and boundary walls built with proper footings, drainage behind, weep vents — engineered to take load.

Clean Joints, Crisp Edges

Resin or mortar joints applied with discipline. Cut edges look straight from the house.

Full Service Area Map

Patios — Porcelain, Sandstone, Block Paving

Porcelain for the modern flat look and easy maintenance; Indian sandstone for the natural textured finish; block paving for drives and high-traffic areas. Each laid on a properly engineered build-up matched to the surface — porcelain on full mortar bed with priming slurry, block paving on screeded sharp sand over MOT.

Retaining & Boundary Walls

Engineered retaining walls with concrete footings, blockwork or brick face, drainage backfill and weep vents. Boundary walls in matching brick or stone to suit the property. Sleeper walls where a softer, faster solution fits the brief.

Drainage & Levels

ACO drainage channels, soakaways sized to the catchment area, connection to existing surface water where permitted, French drains across waterlogged ground. We won't lay a patio without solving the water question first.

Steps, Edges & Detail

Cut stone or porcelain steps, sleeper risers, sett edge restraints, mowing strips between patio and lawn. Detail that makes the garden look intentional rather than assembled.

Residential vs Commercial Hardscape

Domestic gardens favour aesthetic finishes and low-traffic build-ups; commercial spaces (rentals, holiday lets, light commercial yards) need higher load ratings and harder-wearing slabs. We spec to use, not just to look.

Questions

Straight
Answers.

Cost, timeline, guarantees, lifespan, emergency availability — the questions everyone asks, answered before you call.

Ask Yours

How much does a new patio cost in South Wales?

+

Cost depends on slab choice, size, access and any walling or drainage. We quote per m² in writing after a site visit, itemised by sub-base, slab, jointing and drainage so you can see the cost of each element.

How long does a typical garden renovation take?

+

A standard 30m² patio is around 1–2 weeks. A full garden with patio, walling and drainage runs 3–6 weeks. Access and weather drive the programme.

What paperwork comes with a patio?

+

We document the sub-base spec, falls, jointing and slab spec so future surveyors can verify the build-up.

Can you lift and relay a sunken patio?

+

Yes — usually the slabs are fine, the sub-base failed. We lift, dig out, re-base properly and relay using the existing slabs to save material cost.

Do you handle drainage as part of the patio job?

+

Always — drainage is part of the design, not a bolt-on. Falls, channels, soakaways and connections are specced before we dig.

Can you take on a full garden design build?

+

Yes — we handle the hard landscaping in full. For planting and soft landscaping we work alongside garden designers and planting specialists.

Are you insured for retaining wall work?

+

Yes — fully insured (£1m public liability, £10m employers' liability) and we work to engineered specs on any retaining wall above 600mm or holding any significant load.

How long should a patio last?

+

Properly built on a Type 1 MOT sub-base with the right slab spec — 25+ years before any serious attention. Joints may need re-filling at 10–15 years on heavily-used areas.
