Wow, what a fantastic job. The carpets look like new after five years of a family and pets. I can't recommend them enough, I'm delighted. The two guys were very friendly and efficient, and the clean water was topped up all the time. I'm so very pleased.

The service

Inside and out, frames and sills included

A window clean covers the glass, the frames, the sills and the rubber seals, inside and outside. Dull glass makes a room darker than it needs to be, and a streaky finish is the first thing a visitor notices.

Spark Clean Professional cleans windows for homes and business premises across Harrow and London, as a one-off or on a repeat round. Window cleaning is one of the categories on the firm's Google listing, and it is often booked with a deep clean or an end of tenancy clean so the whole property is done in one visit.

Window cleaning services

Standard windows, sash windows, bay windows, French doors, patio doors, skylights, conservatory roofs and glass balustrades are all covered. Frames are wiped down, sills cleared of grime and dead insects, and any spotting from hard London water is worked off the glass rather than smeared around.

Shop fronts and ground-floor commercial glazing are a regular part of the round, cleaned early or late so the shutters are up and the pavement is clear when the shop opens.

Residential and commercial cleaning

For a house or flat the usual booking is every four to eight weeks for the outside, with the inside done less often or at the same time as another clean. For business premises the frequency depends on footfall and the street: a shop front on a main road collects grime far faster than an office window on a side street, and we set the round to suit.

Internal and external window cleaning

The inside is where fingerprints, condensation marks, cooking film and pet noses build up, and it is the side most window cleaners never touch. We clean both sides on request, working inside with cloths and squeegees on dust sheets so nothing drips onto a sill or a carpet. If the carpet is being cleaned the same day, the windows go first so any drips are dealt with by the carpet clean.

Regular cleaning plans

A repeat round is booked at a frequency that suits the property, and you are told when we are coming. Gates need to be unlocked or access arranged for the day; if you are out, the outside can still be done and the inside caught up on the next visit. There is no contract to sign and the round can be paused or stopped by telling us.

Reach and wash cleaning

Upper floors are cleaned from the ground with a water-fed pole system. Purified water is pumped up to a soft brush that scrubs the glass and frame, then the window is rinsed with the same water and left to dry spot-free, because there are no dissolved minerals in it to leave a mark. It reaches windows over conservatories and extensions that a ladder cannot safely get to, and nobody needs to climb.

What the clean covers

The clean covers the glass, frames and sills, inside and out, with purified water for the upper floors so nothing is left to streak. Awkward panes over conservatories and extensions are reached from the ground with the pole. The windows can be done on the same visit as a carpet, upholstery or deep clean.

Window Cleaning questions

Do you clean the inside as well as the outside?

Yes. Say so when you book and both sides are done. Inside work is done on dust sheets with cloths and squeegees so nothing drips onto sills or floors.

How often should windows be cleaned?

For most homes every four to eight weeks on the outside keeps them clear, with the inside every few months. Shop fronts on busy roads need it more often. We set the round to suit the property rather than a fixed schedule.

What access do you need?

Side gates unlocked on the day and, for inside work, someone home or a key arrangement. Upper floors are reached from the ground with a water-fed pole, so no ladders against the house.

Do you clean conservatories and skylights?

Yes. Conservatory roofs, skylights, roof lanterns and glass over extensions are cleaned with the pole system, which reaches over the structure without anyone standing on it.

Can I book a one-off clean?

Yes. One-off cleans before a sale, a viewing, a move or an event are common, and a window clean is often added to a deep clean or an end of tenancy clean on the same visit.

Will the windows dry streaky?

No. Upper windows are rinsed with purified water that has no minerals in it, so it dries without spots. Ground-floor and inside glass is squeegeed and detailed by hand.
