Shard renovations created a new opening for a window to our en-suite. Sean was timely, tidy, clean and really respectful of our property which was greatly appreciated & made post-job cleaning lightening quick, meaning we were able to use the room again immediately. Would recommend Shard & are already planning ahead to consult them for our next project.

Extension Builder in Leigh On Sea
Incorporating 'Green Practices’ into our building process is very important to us and vital in reducing our carbon footprint. Using more environmentally friendly options in the build, including insulation, glazed windows/doors and lighting, will help to ensure the build is overall more energy and cost effective in the long term. Our team is dedicated to bringing our clients high-quality results using traditional building methods whilst being mindful of the environment. We also use, where possible, recyclable and long-lasting materials and dispose of debris by recycling and reusing instead of taking to local landfill eliminating waste and maximising resource efficiency. If you’re looking for a professional building team with a focus on sustainability, Eco Builders is the right choice for you!
