Good job & great customer service

Had my very mossy roof cleaned and treated with a biocide moss retardant. The boys were here for around 4 hours, did an excellent job, cleaned up after themselves and couldn't have been more polite.
Excellent company & great customer service. Cant recommend highly enough.

Brilliant Job!

I had NII Clean out to soft wash my house and garage and clean the roof and gutters in the summer. The team were really helpful and nothing was a problem to them. They even came out again with the cherry picker when I wasn’t happy with the chimney. Turns out it was actually clean but the paint had worn off making it look dirty (so they didn’t really need to come out! ) Their expertise and professionalism were next to none. When on site they worked hard til the job was done. No hanging around! They were also friendly and trustworthy. Mark is also hands on and easy to get in contact with about any issues unlike some bosses! If you want a job done well I recommend NII Clean.
