Wislak Ltd is a London-based construction company led by Operations Director Chris Wiciak and Construction Director Martin Sygnarowicz, who have worked together for over two decades. They manage and deliver a range of projects, from private home renovations including extensions, loft conversions, and basements, to larger residential and mixed-use developments for developers. Their approach emphasizes consistent site management, open-book commercial control, and the use of their own trusted trades, ensuring high standards across all project scales.
The company prides itself on offering a comprehensive service, handling everything from initial design and planning applications, including bringing in structural engineers, to certified mechanical and electrical installations such as solar PV, heat pumps, and MVHR ventilation. They highlight their in-house bricklaying, roofing, and tiling teams as key to their quality finishes, particularly in bathrooms and detailed facing work. This integrated approach allows them to manage projects from demolition and groundworks through to final fit-out and handover, ensuring a smooth delivery process for both homeowners and commercial clients.

Fulham, London SW6
A private home taken back to its party walls and front façade, with a new basement over 30 metres long dug five metres deep and extending under the rear garden. Five bedrooms, four bath and shower rooms, oak throughout.
Wimbledon, London
Existing buildings stripped back, structurally altered, extended and re-roofed, with new steel and timber structure, full M&E and 87 apartments finished alongside communal lounges and landscaped terraces.
Islington N1
We built this house and its basement in 2015. Eleven years later the owner came back to us with water getting in through the walk-on glass terrace and down into the basement. We investigated rather than guessed: the glass roof and box gutter were re-detailed and resealed, a new GRP waterproofing build-up laid under the patio, Delta cavity-drainage membrane and cementitious tanking applied across the steel beam and party wall, and a blocked basement drain opened up, replaced and made good.
Albion Street, London
Demolition of an existing public house and construction of a new-build, mixed-use building in its place: a ground-floor commercial unit designed for future use as a pub or restaurant, with eight one- and two-bedroom apartments on the upper floors, each served by its own balcony.
Notting Hill, London W11
A complete refurbishment of a two-bedroom apartment over two floors, with structural and construction works throughout: a rear extension, a new roof, new balconies and a rebuilt garden. Internally, a new staircase between the floors, a new kitchen, two new bathrooms and a separate WC. Below ground, waterproofing with Delta cavity-drainage membrane and new inspection chambers and drainage.
Clapham, London SW4
A compact but technical job for a dental practice: installation of specialist structural steel beams and the forming of a new staircase opening through the existing structure, carried out to the engineer's details in a building that had to keep working around us.
