Driveway Cleaning & Sealing in Letchworth Garden City, explained

The first useful thing we can do is tell you not to bother. On a sound surface a proper clean is one of the best-value jobs in this trade and the colour underneath is nearly always still there. On a surface that has actually failed, washing it only makes the fault easier to photograph, and we would rather quote you for the repair than take the cleaning money.

Assuming it is worth doing, the price comes in three parts and we show them separately so you can stop at any of them. The clean itself. The re-sanding that block paving needs afterwards.

And the sealing, which is optional, is a separate visit, and is the part people most often decide against once they know what it does and does not do. We are based in Hatfield and this area is part of our normal round. The visit and the written price are free, there is no deposit, and nothing is payable until the work is finished.

We cover the SG6 postcode in Letchworth Garden City, and the rest of Hertfordshire.

What your quote covers

  • An honest look first, and a straight answer on whether a clean will actually fix it
  • One fixed price in writing, no deposit, nothing payable up front
  • A pre-treatment on heavy moss and algae so it dies rather than just moves
  • A rotary flat-surface clean across the whole area, not a striped hand-lance job
  • Block paving joints refilled afterwards, because a clean empties them and an empty joint lets blocks shift
  • Sealing as a return visit once the surface is properly dry, where you are having it sealed

Choosing driveway cleaning & sealing in Letchworth Garden City

A sealed drive is not sealed for good, and it helps to know the cycle before deciding whether it is worth it. Three to five years is the usual span, shorter where the drive gets a lot of direct sun and heavy traffic, longer on a shaded, lightly used frontage.

The tyre lines will tell you before anything else does. Wear concentrates where the car runs and turns, so that is where the finish dulls first and where you can judge whether another coat is due.

Whether to seal at all is a separate question from whether to clean. The clean is what takes algae, moss and traffic film out of a tired surface in Letchworth Garden City. The seal steadies the joint sand, deepens the colour and makes spills easier to lift, for a few years at a time.

From first visit to finished job

  1. Step 1

    Quick Look

    We assess the surface and tell you honestly whether a clean and seal will do the job.

  2. Step 2

    Written Quotation

    A fixed written price, agreed before we start.

  3. Step 3

    Deep Clean

    The drive is jet washed, and moss, weeds and staining are cleared off.

  4. Step 4

    Re-Sand

    Block paving joints are refilled with kiln-dried sand so the surface locks up.

  5. Step 5

    Seal

    Once dry, we seal the surface to protect it, and you settle up when you are happy.

What happens on site in Letchworth Garden City

Heavy moss and algae are pre-treated and left to die off, so the clean lifts dead growth rather than live growth that would return from the roots.

The wash itself is done with a rotary flat-surface cleaner, which gives an even finish across the whole drive and avoids the striping that a hand lance can leave.

Every joint is then refilled with fresh kiln-dried sand, included as standard, since cleaning takes the old sand out along with the dirt. Sealing follows on a return visit once the surface is thoroughly dry, applied evenly and allowed to cure before use.

What affects the price in Letchworth Garden City

We do not publish a rate per square metre, because the number would be wrong for most properties. The survey is free and the price you get afterwards is fixed and in writing. These are the things that move it:

  • The area being cleaned, and how much of it is intricate or awkward to get a rotary head across
  • How much moss, algae and weed has built up, and whether it needs pre-treating
  • The surface type, since block paving carries the re-sanding and concrete does not
  • Whether you are having it sealed, and which sealer suits the surface
  • Any repairs the surface needs first, which we would quote separately
  • Access to water and power, and where the run-off can safely go

Looking after driveway cleaning & sealing

Expect to reseal every three to five years, judging it by the tyre lines rather than the calendar, since sun and traffic decide the pace more than time does.

Between coats, keep leaves brushed off and the gullies and channels clear, and treat green growth early with a proper biocide rather than letting it establish itself.

Keep strong household chemicals and neat bleach off the paving. They bleach the colour unevenly and the resulting marks are considerably harder to fix than the algae ever was.

Driveway Cleaning & Sealing in Letchworth Garden City: Common Questions

Do you work in Letchworth Garden City?

Yes, SG6 is in our area. We are based in Hatfield and the survey is free.

How long does sealing last?

Three to five years as a rule. Less on a sunny, heavily used drive, more on a shaded one that sees little traffic.

How do I know when to reseal?

Look at the tyre lines. Wear concentrates where the car runs and turns, so the finish dulls there first.

Is sealing necessary?

No. It steadies the joint sand, deepens the colour and helps spills lift off, but it is optional and it is not a repair.

Does cleaning remove the joint sand?

Yes, which is why re-sanding every joint with fresh kiln-dried sand is part of the job rather than an extra.

Can it all be done in one visit?

Usually not, as sealer needs a dry surface. Cleaning and sealing are normally separate visits.
