About LMDEC LTD - Builders - Property Renovations Extensions and Alterations

LMDEC is a family-run South London building and renovation company, established in 2014. It works on kitchens, bathrooms, extensions, loft conversions, period restorations and wider home refurbishments. The company describes its general trades as in-house, including demolition, structural steel, carpentry, plastering, tiling and decorating; specialist gas and electrical installations are managed with certified subcontractors.

Projects begin with a site visit and an itemised fixed-price quote, which the company says it provides within 48 hours. A project manager coordinates the work and LMDEC limits itself to three projects at a time. Its published process includes a final clean and handover.

LMDEC states that it carries £2 million public liability insurance and provides a two-year workmanship warranty, with a six-month check-in. It also mentions manufacturer warranties and examples of work on Victorian and Edwardian homes. The company lists work across South London, including Wandsworth, Richmond, Chelsea and Croydon.
