Specialized Exterior Cleaning Solutions
Roof Cleaning & Moss Removal
Your roof is your property's first line of defense against the elements, yet it's often the most neglected surface. Moss, algae, lichen, and debris accumulate over time, trapping moisture, lifting tiles, and accelerating deterioration. Our professional roof cleaning service removes all organic growth and restores your roof to optimal condition.
We use specialized soft washing techniques that are gentle on tiles while being highly effective at removing moss and preventing regrowth. Our PASMA/IPAF certified team works safely at height, and we treat your roof with biocide to inhibit moss return for years, extending your roof's lifespan and maintaining your property's value.
Gutter Cleaning & Maintenance
Blocked gutters cause water overflow that damages fascias, soffits, walls, and foundations. During heavy Northern Ireland rainfall, clogged gutters can lead to serious water ingress and costly repairs. Our thorough gutter cleaning service removes all debris, ensures free-flowing drainage, and protects your property from water damage.
We clean downpipes, check for leaks and damage, and can install gutter guards to minimize future maintenance. Our team works safely at height with proper access equipment, and we dispose of all debris responsibly, leaving your gutters clear and your property protected.
Pressure Washing Specialists
Transform your driveways, patios, paths, and exterior surfaces with our professional pressure washing service. Years of dirt, oil stains, algae, and grime are removed to reveal the original surface beneath. We use industrial-grade pressure washing equipment with adjustable settings to suit every surface type.
Whether it's block paving, concrete, tarmac, natural stone, or timber decking, we apply the correct pressure and technique to clean effectively without causing damage. After cleaning, we can apply sealants to protect surfaces and make future maintenance easier.
Soft Washing Technology
For delicate surfaces like render, painted walls, uPVC cladding, and conservatory roofs, high-pressure washing can cause damage. Our soft washing technique uses low-pressure application of specialized cleaning solutions that gently remove dirt, algae, and organic growth without harming the surface.
Soft washing is particularly effective for cleaning render, K-Rend, painted surfaces, and conservatories. The cleaning solution penetrates deeply to kill organic growth at the root, providing longer-lasting results than pressure washing alone. Your property looks refreshed without the risk of surface damage.
