 Trustindex verifies that the original source of the review is Google. We had our front garden tiles and back garden patio cleaned recently by Michael.
We are absolutely delighted with the results, it looks like new and Michael even managed to get some very stubborn algae and oil stains off the tiling. I found Michael to be extremely professional, helpful and gave great advice, he explained everything so well. I would highly recommend Cleaning Doctor ! ! Thank you so much

Bryan and his team did an absolutely fantastic job cleaning my house over the past two days. They thoroughly cleaned everything — from the roof, walls, and all windows to the driveway — and the results are truly outstanding.

They worked extremely hard, carefully, and professionally throughout the entire process. What impressed me the most was their incredible attention to detail. During the work, they noticed that the end cap of my gutter was missing, and kindly went out of their way to get a replacement and install it for me. They also spotted that a roof tile was missing and helped replace it as well — something I really appreciate.

It’s not easy to find a team that is not only professional but also genuinely helpful and proactive like this. I’m extremely happy with the results and very grateful for all their effort over the past two days.

I would highly, highly recommend Bryan and his team to anyone looking for top-quality exterior cleaning services.

Why Seal Your Driveway?

The benefits of our professional sealing services.

Delays Weed Regrowth

Sealing hardens the jointing sand, which prolongs the return of weed regrowth.

Prevents Oil Stains

Sealed surfaces repel oil, grease, and fuel spills, making them easy to wipe away before they stain the paving.

Enhances Colour

Sealers can restore the original colour of faded paving, giving it a "wet look" or a natural matte finish as desired.

Stabilises Blocks

By binding the sand, the sealant prevents blocks from wobbling or sinking, maintaining the structural integrity of your drive.

UV Protection

Our SmartSeal products protect against UV rays, preventing further colour loss and fading from the sun.

Restores Faded Colour

Brings tarmac back to a rich, deep black finish, reversing UV fading and years of weathering.

Prevents Surface Cracking

Seals hairline cracks and protects against further damage from frost, water, and heavy use.

Easier Maintenance

A sealed surface is much easier to sweep and clean, as dirt sits on top of the sealant rather than grinding into the stone.

Price Promise

The price quoted includes all labour, equipment, and sealing materials – no hidden extras. In Clontarf or further out, there are no surprises on the invoice.

Fully Insured

We carry full public liability insurance, giving you complete peace of mind while we work on your property.

Our Process

Clean, Sand & Seal

A comprehensive two-stage restoration for your paving. Sealing is weather dependent — the paving has to be completely dry before any sealer can go down.

Sweeping kiln-dried sand into block paving joints

1. Deep Clean & Re-Sand

First, we pressure wash the area to remove all dirt, moss, and old sand. The paving then needs to dry out completely before we sweep in fresh, sterile kiln-dried sand to refill the joints. Different surfaces require different drying times. If your patio only needs the clean for now, see patio cleaning in Dublin North.

Deep Clean: Removes all contaminants

Re-Sanding: Stabilises the paving

Drying: Different surfaces require different drying times

2. Sealant Application

We apply two coats of high-quality SmartSeal acrylic or solvent-based sealer. This penetrates the sand, hardening it like mortar, and coats the surface. We only do this on a dry day with a dry forecast ahead of it, so the sealer can cure properly.

Two Coats: For maximum durability

Hardens Sand: Prolongs the return of weed regrowth

Dry Weather: Needs 24 dry hours

Waterproof

Beads water on surface.

Oil Resistant

Protects against leaks.

Frequently Asked Questions

Common questions about our sealing services.

How soon can you seal my driveway or patio?

That comes down to the weather rather than how busy we are. Once the paving has been cleaned it has to dry the whole way through before any sealer can go down. Different surfaces require different drying times, and cold, damp or shaded spots take longer again, so we'll let you know what to expect for yours. If it rains while it's drying, the clock starts again. That's why sealing is booked as two visits, and why we can't commit to a firm sealing date until we can see the forecast.

Why can't you just seal it while it's still damp?

Because it would ruin the finish. The sealer forms a film over the surface, so any moisture still sitting in the paving or the jointing sand gets sealed in underneath. It shows up as a cloudy, milky-white bloom and the sealer lifts and peels within months. Stripping and redoing a failed seal costs far more than waiting a few extra days, so we'll always hold off rather than seal in the wrong conditions.

What happens if it rains after you've sealed?

We only seal when the forecast gives us a clear dry window, because the sealer needs roughly 24 dry hours to cure. Once it has cured, rain is no problem at all — that's exactly what the sealer is there for. If the forecast changes before we start, we'll ring you and move the date rather than take the risk.

Can you seal at any time of year?

In practice, sealing works best from late spring through to early autumn, when we get longer dry spells and warmer surface temperatures. Through the winter months the paving rarely dries out enough between showers, and low temperatures slow the cure right down. We're happy to clean and quote at any time of year, but we'll be straight with you about when the sealing itself is realistically going to happen.

How long do I have to stay off the drive?

For pedestrian traffic, usually 3-4 hours. For vehicles, we recommend keeping them off for 24 hours to allow the sealant to fully cure and harden.

Will it make the surface slippery?

No. We can add an anti-slip additive to the final coat of sealant. This microscopic grit provides grip without changing the look of the surface, ensuring safety in wet conditions.

Does it stop weeds completely?

No, but it prolongs the return of weed regrowth. The sealant hardens the sand in the joints, making it harder for weeds to take root. Any surface weeds that do appear will be shallow-rooted and easy to remove.

Can you seal tarmac driveways?

Yes. Tarmac has different problems to block paving. Over time, UV and weathering fade it to a dull grey, and frost and water open up hairline cracks across the surface. After a thorough clean, we apply a specialist tarmac restoration sealer that brings the drive back to a rich, deep black and seals those hairline cracks, protecting it against further damage from frost, water and heavy use. Deeper cracks, potholes or broken edges need repairing before sealing, and we'll point those out when we quote.

Can you seal concrete driveways?

Yes. We use specific concrete sealers for pattern imprinted drives. Each surface requires a different product for best results, so tarmac, concrete and block paving are each sealed with their own sealer.

How often does it need re-doing?

A good quality acrylic sealer typically lasts 3-5 years depending on traffic and weather exposure. A simple top-up coat can then be applied to restore the protection.
