Yes. Need Cleaning is fully insured for domestic and commercial exterior cleaning.

Every job is different, so we quote after looking at the size, surface, condition and access. Quotes are free and there's no obligation.

Yes. We clean for homeowners, landlords, letting agents and commercial customers. No job is too big or too small.

We cover the UK. Get in touch with your postcode and we'll confirm we can get to you.

Not as a rule. The right method depends on the roof material and its condition. After an inspection we may recommend careful manual moss removal, controlled steam cleaning, softwashing or a mix of these.

Most of the improvement is visible on the day, but some treated organic staining keeps fading over the following weeks. We'll tell you what to expect for your roof before we start.

Yes. Removing loose moss means less debris falls into the gutters. We can also clear the gutters as part of the same job so nothing dislodged is left behind.

There's no fixed interval. Shade, nearby trees, roof pitch and local conditions all change how fast growth returns. We'll advise on sensible maintenance once we've seen the roof.

Yes, where you can. Clearing furniture, bins, ornaments and vehicles lets us clean the whole area evenly. Let us know about anything heavy before the day.

Usually. A deep clean lifts loose jointing sand, so re-sanding with kiln-dried sand is normally recommended and can be included in your quote once the surface is dry.

Often not. The paving needs to be fully clean and dry before sealing, so depending on the surface and the weather, sealing may be a second visit.

We can use our own water supply where required. We'll confirm access and water needs when we quote.

No. Softwashing relies on a suitable cleaning treatment applied at low pressure rather than the force of the water. It's usually the better choice for render and coated walls.

Algae, organic growth and general dirt usually respond well. Rust, paint damage, cracks or permanent discolouration may stay, and we'll tell you before we start.

Light weathering is usually fine. Loose, cracked, blown or flaking render may need repairing first, as cleaning can't fix a defect in the wall or coating.

It depends on shade, moisture and nearby plants. No wall stays clean for ever, but the treatment helps slow the return of growth compared with washing alone.

Plants growing out of them, water spilling over the edge, staining below joints and debris at the downpipe outlets are the usual signs.

No. Sealing is optional and doesn't suit every surface. We look at the paving type, its condition and any previous coatings before recommending it.

Most sealers need a clean, dry surface and suitable weather to bond and cure properly. Sealing too soon can trap moisture and spoil the finish.

We clean and maintain. If we spot an obvious defect while we're working, we'll show you so you can arrange a repair.
