Driveway cleaning in Macclesfield
In short
Cleaning a drive properly rather than blasting it — sensible pressure, moss and algae treated rather than just knocked off, and, on block paving, the joints re-sanded afterwards. A great many drives people are pricing up to replace only need this.
Also called: Jet wash driveway · Pressure wash drive · Clean block paving · Driveway wash
Signs you need this
- Block paving that has gone dark green or black with algae
- Joints full of moss with weeds coming through
- A drive that looks tired but is completely solid underfoot
- Imprinted concrete that has gone flat and chalky
- Preparing to sell or let a property
- Wanting to know whether the drive needs replacing or just cleaning
A large share of the drives that get quoted for replacement are structurally fine and simply filthy. Block paving in particular ages cosmetically long before it ages structurally: the joints darken and empty, moss establishes, weeds follow, and a drive that is dimensionally perfect starts to look finished. Cleaning, re-sanding and — where appropriate — sealing it costs a fraction of relaying, and it is the first thing worth checking.
How a drive is cleaned matters far more than whether it is cleaned, and this is the single most useful thing on this page. A pressure washer lance held close, or a rotary surface cleaner run at full pressure, will strip the kiln-dried sand out of block paving joints in seconds. Joints are what hold a block pavement together — take the sand out and the blocks lose their interlock and start moving under traffic. Drives are routinely wrecked by being cleaned.
So the correct sequence is: treat, clean at a sensible pressure, dry, then re-sand. Treating first means killing the moss and algae with a proper biocide rather than blasting the visible growth off and leaving the spores, which is why an untreated drive is green again within months. Cleaning at a moderate pressure with a surface cleaner, kept moving, lifts the dirt without excavating the joints. And on block paving, re-sanding and vibrating afterwards is not optional — it is what puts the pavement back together.
Different surfaces want different treatment and it is worth being specific. Block paving: moderate pressure, then re-sand. Imprinted concrete: gentle, and any surviving sealer will need stripping and recoating afterwards. Resin bound: light wash only, because a close lance damages the mat and can break the bond. Natural stone: gentle, particularly on soft or reclaimed sandstone where high pressure erodes the surface. Tarmac: light — high pressure strips the fines out and accelerates ravelling. Gravel: it does not get pressure washed at all.
Where the water goes is a real consideration and one that responsible contractors think about. Cleaning water carries silt, biocide and hydrocarbons, and it should not simply be flushed into a surface-water drain that discharges to a watercourse. Directing it to a soft area, a foul gully where appropriate, or containing and filtering it is the correct approach — particularly here, where Cheshire East attributes part of Macclesfield's flooding record to a stressed and partly unmapped culverted drainage network.
One honest note about what cleaning cannot do. It will not fix a drive that is moving, sunken, cracked through or holding water — it will just make the faults easier to see. Anyone proposing to clean and seal a failing drive rather than mention the failure is selling a cosmetic over a structural problem. A clean should come with a straight assessment of what else the drive needs, including nothing.
What the job covers
- An assessment of what the drive actually needs before cleaning it
- Moss and algae treated with a biocide rather than just blasted off
- Pressure and method matched to the surface, not one setting for all
- Surface cleaner kept moving so joints are not excavated
- Block paving joints re-sanded and vibrated after cleaning
- Weeds removed and treated at the root
- Wash water directed responsibly rather than flushed to a watercourse
- A straight report on anything structural the cleaning has revealed
What it costs
We don't publish a price for this yet, because a number pulled out of the air is worse than no number at all — your contractor has to honour it. On driveways it would also be close to meaningless: the groundworks are usually the biggest single factor, and how deep the dig has to go varies enormously house to house. You'll get a firm price for your actual job when they ring you back, before any work starts. The quote itself is free and there's no obligation either way.
Common questions
Will jet washing damage my drive?
It can, easily. High pressure held close strips jointing sand out of block paving, erodes soft sandstone, removes fines from tarmac and damages resin. The damage is not always obvious on the day — a block drive can look immaculate after cleaning and be visibly loose six months later. Sensible pressure, the right technique and re-sanding afterwards are what make it safe.
Do the joints really need re-sanding afterwards?
On block paving, always. The kiln-dried sand in the joints is what creates the interlock that holds the pavement together, and cleaning inevitably removes some of it. Re-sanding and vibrating it back in is part of the job, not an extra. A cleaning quote that does not mention it is quoting for half the work.
How often should a driveway be cleaned?
Once every year or two suits most drives, and a shaded, north-facing or tree-covered one may want it annually. More frequent than that is usually a sign of a drainage problem keeping the surface damp. Sweeping regularly and keeping leaves off does far more good than an aggressive clean every spring.
The moss comes back within months. Why?
Because it was blasted off rather than killed. Pressure alone removes the visible growth and leaves the spores in the joints and the surface pores, so it regrows as soon as conditions suit. Treating with a proper biocide before and after cleaning is what makes the difference between a season and a couple of years.
