Driveway Cleaning & Sealing in Stevenage, 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 SG1 and SG2 postcodes in Stevenage, 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 Stevenage

There are two ways to pressure wash a drive and they produce noticeably different results. A hand lance cleans in overlapping arcs, and unless the operator is very careful you end up with striping, lighter bands where the jet lingered and darker ones where it did not.

A rotary flat-surface cleaner runs at a fixed height with the spray enclosed, so it takes the same amount off everywhere it passes. The finish is even across the whole drive rather than patchy, and it keeps the dirt and water contained instead of spraying it up the wall and across the windows.

Before any of that, it is worth establishing whether cleaning is the right job at all. A drive in Stevenage that is simply dirty, with algae, moss and traffic film worked into the texture, cleans up well and can go years longer. One with sunk blocks or failed edges needs repair, and washing it only makes that clearer.

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 Stevenage

Heavy moss and algae are pre-treated first so that the growth dies off properly. Blasting it off while it is still alive removes what you can see and leaves the roots, which is why some drives are green again within months.

The clean itself is done with a rotary flat-surface cleaner for an even finish across the whole area. Taking dirt out of block paving inevitably takes the joint sand with it, so re-sanding is part of the job rather than an extra line on the invoice: fresh kiln-dried sand brushed into every joint and worked in.

If you are having the drive sealed, that waits for a dry surface and is normally a separate return visit rather than something squeezed into the same afternoon. The sealer is applied evenly and left to cure before the drive goes back into use.

What affects the price in Stevenage

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

A sealed drive generally wants redoing every three to five years, sooner where it gets a lot of sun and traffic. The tyre lines tell you first, because that is where the wear shows.

In between, keep leaves brushed off and the gullies and channels clear. If green growth starts to appear, treat it early with a proper biocide rather than waiting until it is established.

Keep strong household chemicals and neat bleach off the paving. They bleach the colour unevenly and leave marks that are considerably harder to put right than the algae you were trying to remove.

Driveway Cleaning & Sealing in Stevenage: Common Questions

Do you clean driveways in Stevenage?

Yes, SG1 and SG2 are both in our area. We are based in Hatfield and there is no charge to come and look.

Will jet washing damage my paving?

Not done properly. We use a rotary flat-surface cleaner at a controlled height rather than a hand lance held close, which is what causes damage and striping.

What is striping?

Light and dark bands left by a hand lance where the jet lingered unevenly. A rotary cleaner takes the same amount off everywhere, so the finish is even.

Why does the sand have to go back in?

Because cleaning block paving takes the joint sand out with the dirt. Empty joints let blocks move and weeds root, so we re-sand as standard rather than charging for it separately.

Can you clean and seal on the same day?

Normally no. Sealer needs a properly dry surface, so it is usually a return visit.

Do you charge to come and look?

No. The survey is free and so is the written quote.
