Roof Cleaning Harpenden
Your roof is one of the most exposed parts of your home, constantly facing harsh weather conditions. Over time, organic growth such as moss and lichen begins to take hold, trapping moisture and accelerating the deterioration of tiles. What starts as a cosmetic issue can quickly lead to more serious problems if left untreated. Our service is focused not just on cleaning, but on preserving the integrity of your roof and extending its lifespan.
What Is Driveway Restoration?
From roofs to driveways, paths and patios
Driveway restoration is a comprehensive process designed to clean, repair, refresh and protect your existing surface. Rather than removing and relaying your driveway, restoration focuses on improving its condition and extending its lifespan. The result is a driveway that looks dramatically improved and is protected against further deterioration.

Every restoration project begins with a detailed assessment. We evaluate the condition of your driveway, identify areas requiring attention, and recommend the most effective solution.
Preparation is key to long-lasting results. We never rush this stage. Thorough cleaning and correct surface preparation ensure proper adhesion of sealants and even colour application.
Once restored and sealed, your driveway benefits from enhanced appearance and improved resistance to the elements.
