They did a top class job for us  we are very thankful and would highly recommend. Donal called out to access the job. Then  Ian and Paul power washed the whole house and footpaths.  Also the roof was treated for moss. Donal painted the chimney.  A lovely pleasant and obliging team.

 recommendsTrustindex verifies that the original source of the review is Facebook. We recently had our roof, tarmac, footpaths, kerbs, and patio professionally cleaned and treated, and the results were absolutely outstanding. From start to finish, Donal and his crew were incredible to deal with.

They worked tirelessly over several days, arriving early each morning and maintaining a consistently high standard of professionalism throughout. Not only was their work ethic impressive, but they were also genuinely pleasant and easy to have around — something that really stood out.

The transformation of our outdoor areas has been remarkable. Everything looks refreshed, spotless, and well cared for. It’s clear they take great pride in what they do, and it shows in the final result.

I would highly recommend their services to anyone looking for this type of work. Wishing Donal and his team continued success — we certainly won’t be looking anywhere else in the future!

Our Process

Pure Water Perfection

The science behind a smear-free shine.

1. Water Purification

Tap water contains minerals that leave white spots when they dry. We filter our water through a multi-stage system to remove all impurities.

De-ionisation: Removes minerals

Pure Water: Strips dirt without residue

Eco-Friendly: No chemicals used

2. Reach & Wash

We pump pure water up carbon fibre poles to a brush head. This scrubs the dirt from the glass and frames, which is then rinsed away.

High Reach: Up to 60ft

Safety: Feet on the ground

Frames Cleaned

Standard part of service.

Spot Free Dry

Dries naturally without marks.

Frequently Asked Questions

Common questions about our window cleaning services.

Why do you leave the windows wet?

We use 100% purified water which has no minerals or impurities. Because the water is pure, it will dry naturally without leaving any spots, streaks, or marks. There is no need to squeegee or dry them by hand.

Do you clean the frames?

Yes! Cleaning the frames and sills is a standard part of our service. Our brush heads are designed to scrub the uPVC frames and sills as well as the glass, leaving the whole window unit sparkling.

Can you clean upstairs windows?

Absolutely. Our carbon fibre pole system can reach up to 4 storeys high, allowing us to safely clean upstairs windows, windows above conservatories, and skylights from the ground.

Do you clean solar panels?

Yes, we are experts in solar panel cleaning in Cork. Dirt, dust, and bird droppings can reduce solar panel efficiency by up to 25%. Our pure water system cleans them safely without chemicals that could damage the surface.

How often should I get my windows cleaned?

For residential properties, we typically recommend a clean every 4 to 8 weeks to maintain a sparkling finish. For commercial properties, more frequent cleaning may be required. We can arrange a schedule that suits you.
