Case study: Indian stone patio in Altrincham.
A repeat customer -- Bob -- after we'd already installed his artificial grass. He wanted the old gravel seating area upgraded to a proper Indian stone patio. Dug out the old gravel, 2 tons of MOT subbase, Indian sandstone laid mortar-jointed over 2 days. £3,100 fixed.

Why Bob called us back.
Bob is one of our favourite kinds of customer -- a repeat. We'd already installed his artificial grass earlier in the year and the relationship was solid. When he decided the old gravel seating area at the rear of his garden had run its course, the call was easy: he wanted us back, this time to lay an Indian stone patio as the upgrade.
The brief was simple: gravel out, proper Indian sandstone in, finished to the standard he'd seen on the grass install. Fixed at £3,100, three days on site.
What we did.
Indian stone is a different beast to budget flagging. The flags are heavier, the layout pattern matters, and the joints are mortar-pointed rather than butt-joined -- so the prep and the laying both take longer.
The build sequence:
- Dug out and removed the old gravel and any weeds underneath
- Stripped back to a clean sub-grade
- Laid 2 tons of MOT type-1 for the subbase
- Levelled the MOT with a whacker plate and called the falls away from the property
- Set out the Indian sandstone pattern -- mixed flag sizes laid in the standard random / project pattern
- Laid the stone bedded on mortar, working from a reference line outward
- Cut around obstructions and edges with a wet saw for clean finishes
- Mortar-pointed every joint -- the long, fiddly day-3 detail work that separates a £3k Indian stone patio from a £700 cowboy job
- Clean-down, walkaround with Bob, handover
End result: a premium Indian sandstone patio that ties in with the artificial grass we'd laid earlier. The garden now reads as a single coherent design.

Day 1: 2 tons of MOT laid, levelled, whacker-compacted with falls.
Days 1-2: Indian sandstone laid mortar-bedded in the project pattern.
Day 3 finish: every joint mortar-pointed. Patio ties cleanly into the existing artificial grass.What Bob said.
After completing our artificial grass install, we asked the guys to lay an Indian stone flag to our rear garden. Once again, 5 out of 5! Thank you.

What we actually built into this Indian stone install.
Why mortar-bedded + mortar-pointed (not sand-bedded butt-jointed)
For Indian sandstone -- and any premium natural-stone patio -- the right method is mortar-bedded on the subbase with mortar-pointed joints rather than dry sand. Reasons: (1) natural stone flags vary slightly in thickness, and mortar bedding absorbs that; (2) mortar-pointed joints stop weed and moss ingress for years; (3) the visual finish reads as a "proper" patio rather than a budget paved area. The extra labour cost is what you're really paying for at this price point.
Project pattern -- mixed flag sizes laid randomly
Indian sandstone is usually supplied in a mix of sizes -- 600x600, 600x300, 600x200 etc -- specifically because the intended layout is a random / project pattern. We set this out carefully on day 1 so the pattern looks deliberate rather than chaotic, with no four-corner joints and no long unbroken lines across the patio.
2 tons of MOT subbase -- why even Indian stone needs it
Some installers skip subbase prep on natural stone jobs because the flags are heavier. We don't. A proper compacted MOT type-1 subbase is what stops Indian stone settling unevenly over winter freeze-thaw cycles. The same subbase logic applies as on budget flagging -- just with heavier flags on top.
Falls + drainage for a natural stone patio
Natural stone is more sensitive to standing water than concrete flags -- prolonged pooling can mark the surface. We always lay Indian stone with a fall of around 1:80 away from the property and any structures, so water sheets off cleanly.
Repeat customer -- why they came back
Bob had us out for the artificial grass install earlier in the year. The grass tied into where his rear gravel area met the lawn. When he decided to upgrade the gravel to a proper patio, he asked us to come back rather than start over with a new contractor. Same crew, same standards, same finish -- which is exactly the point of building a 3-founder firm with no subcontractors.

Altrincham -- Manchester
Altrincham is a substantial town in Trafford -- substantial mix of period housing stock with rear gardens that suit a proper patio. Indian sandstone is one of the most popular choices for this kind of garden because it's premium without being ostentatious.
We're based in Westhoughton, about 25 minutes from Altrincham.
Questions homeowners ask about projects like this.
Can I get an Indian stone patio for around £3,100?
This Altrincham project came in at £3,100 fixed -- includes the dig-out, 2 tons of MOT subbase, Indian sandstone flags, mortar bedding + jointing, and 3 days of labour. Comparable Indian stone patios in the North West typically sit in the £2,500-£6,500 range depending on coverage and flag spec.
How long does an Indian stone patio take to install?
This Altrincham project took 3 days end to end. Larger Indian stone patios (50m+) typically run 4-6 days; the mortar-pointing day is non-negotiable regardless of size.
Indian sandstone vs porcelain vs budget concrete flags?
Indian sandstone is the middle ground -- premium natural stone, far cheaper than porcelain, far more characterful than concrete. It can stain if not sealed properly but holds its appearance for decades when laid right. Porcelain is more uniform and stain-resistant but costs significantly more. Concrete flags are the budget option (like our Preston job) -- great value, less premium feel.
Should I seal Indian sandstone after install?
Optional but recommended. A proper natural-stone sealer reduces stain risk (red wine, BBQ grease, leaf tannins) and slows colour fade. We can advise on product choice at the survey but most homeowners self-apply 6-8 weeks after install.
Do I need planning permission for an Altrincham Indian stone patio?
Almost never for a rear garden patio. Front-garden non-permeable paving over a certain area can trigger planning but rear-garden patios fall under permitted development.
