Station Road and St Ann's Road, a short walk from Harrow on the Hill station, are where many of our conversations about driveways begin. As a family-run paving company Harrow homeowners recommend to their neighbours, we work everywhere from the Victorian terraces of Wealdstone and Greenhill to the interwar semis of Kenton and Headstone. A typical job is a new driveway Harrow Weald families can park two cars on, or a tidy block paved frontage off Pinner Road. Being a Harrow driveway company with commercial experience, we also handle car park surfacing Harrow businesses, surgeries and places of worship depend on. Every enquiry across HA1, HA2 and HA3 starts with a free, no-obligation site survey.
Most Harrow clients come to us wanting block paving driveways, and we lay them in a wide range of colours and patterns from manufacturers such as Marshalls, Brett and Bradstone. Not every frontage needs paving edge to edge, though. Sandstone paths and borders can soften a busy drive, while gravel or shingle panels held behind proper edging let rainwater soak away and suit a more relaxed front garden. We are happy to mix these finishes on one plot. Every driveway we build is backed by our 10-year guarantee, and the materials carry their manufacturers' own guarantees too.

From a small reinstatement to a complete driveway, forecourt or car park, we have the team and the equipment to do the whole job.
Red or black tarmacadam, a quick and low-maintenance way to upgrade your frontage. Add block paved borders or decorative chippings rolled into the surface for a smarter finish.
Choose from a wide range of colours and patterns to suit your house. Laid on a properly compacted base with firm edge restraint, so the blocks stay level and do not sink.
A smooth, permeable finish that lets rainwater drain through, with little upkeep. Also available as resin bonded or tar and chip for a textured, natural look.
Walls and brickwork, brick pillars, steps and planters built to frame your new drive, so the whole frontage looks finished, not just the surface.
Potholes, sunken blocks, cracked concrete and failed edges put right, or a worn surface lifted and replaced on the existing base where it is sound.
Patios and paths, kerbs, channel drains and soakaways. Drainage provision is designed in, in line with current planning rules.



Water gets in, freezes and breaks the surface up further every winter.
Usually a sign of a thin or failed sub-base, often with wheel ruts where the car parks.
Standing water or run-off towards the house points to poor falls or missing drainage.
Gaps have opened up and the jointing sand has washed out.
A narrow drive or old crazy paving that no longer suits two cars.
Without firm edge restraint, the surface spreads and breaks away at the sides.
10-year guaranteeHarrow is built on heavy London Clay, which swells in wet winters and shrinks in dry summers, so a drive laid on a thin base will rut and sink. We dig out to firm ground and lay a properly compacted sub-base before any surface goes down. Around Harrow School the problem is gradient: West Street, Byron Hill Road and Grove Hill are steep, so falls, channel drains and firm edge restraint really matter. In West Harrow, the late Victorian and Edwardian terraces have short frontages with little space for a car and bins together. Towards Rayners Lane, many 1930s Metroland semis still carry original concrete or tired crazy paving that has to be broken out and removed first, with run-off directed away from the house.
We cover the whole of Harrow, from Greenhill and the town centre out to Wealdstone, Kenton, Harrow Weald, West Harrow and the streets in between.
We also cover these nearby areas with the same team and the same guarantees.

Prices in Harrow depend largely on the house. A short terrace frontage in Wealdstone needs less material than a wide 1930s plot in Kenton, but access can be tighter. Dig-out depth on London Clay, removing an old concrete or crazy paving drive, drainage on a sloping site and whether you need a dropped kerb from Harrow Council all affect the final figure. The best way to get an accurate price is a free no-obligation survey, so call us on 020 8226 6494.

Straight answers to the questions we are asked most. If yours is not here, call us.
Yes. Sloping drives are common on the Hill and they can be built well with the right preparation. We set falls so water runs away from the house and garage, add channel drains at the bottom of the slope where needed, and use strong kerbs or edging to stop the surface creeping downhill. Block paving and textured tarmac both give good grip, and we will advise which suits your gradient during the survey.
Not usually, as long as the new surface is permeable or drains onto a lawn or border within your property. A new or replacement hard surface of more than 5 square metres in a front garden that sends water onto the road does need planning permission. We design to the current rules and explain the drainage at your free survey. A new dropped kerb is a separate application.
No. On every new driveway we supply all materials, sourced from leading manufacturers, and they come with the manufacturer's own guarantee. You will not need to buy anything for your driveway installation.
Yes. We have wide experience of what works best for each situation in terms of use and budget, and can nearly always suggest something that will improve your driveway, path, patio or garden. We are happy to visit, give you our advice and supply a free, competitive quote.
A channel drain is installed across the width of the driveway at its lowest point, usually where the drive meets the garage or the pavement, and it is connected to a soakaway or a suitable drainage run.
Loose gravel is not a good choice on a sloping drive, because it rolls downhill when cars drive over it. On a slope we recommend tarmac, block paving or a resin bound surface instead.
A new driveway should be at least 10 to 12 feet wide (3 to 3.6 metres). Anything narrower makes it awkward to get in and out of the car.
A well compacted, crushed stone sub-base on a firm, prepared subgrade. The sub-base is the foundation of the driveway, so we dig out to firm ground and choose the base material to suit your soil and the surface going on top.
It depends on how long you want it to last, how much maintenance you are happy to do, the look you want and how much traffic it will take. For a hard-wearing, attractive surface with little upkeep we usually recommend tarmac or resin bound. Block paving offers the widest choice of colours and patterns.
