Lemon Drainage Services Ltd
4.7(50 reviews)
Highly RatedRecommended
Formed in 2015 as a private ’Integrated Drainage Services Company’, we set out with a single vision. To offer professional and high quality, but affordable drainage services where the key point is putting the customer first. Unlike many larger drainage service providers who treat their clients as a number and a ‘£’ sign, we do not wish to grow to such a scale where the focus on providing our service with a personal touch is lost.

Do I need drain clearance or drain repair?
