J L Windows

JL Windows is a family-run double-glazing company based in Leyton, supplying and fitting windows, doors, skylights and conservatories for homes across London. Its range includes uPVC, aluminium, sash and flush-sash windows, plus composite, patio, bi-fold and sliding aluminium doors. The company says it has more than 15 years of industry experience; its surveyors and fitting staff have over 25 years in double glazing.

For repairs, the team supplies and fits replacement parts, repairs latches, locks and hinges, and can replace misted glazing units. It describes its approach as pressure-free, with one price rather than sales discounts. For a conservatory, it says it handles the project from the initial design visit through installation and planning permission.

JL Windows states that its work is guaranteed and advertises FENSA registration with a 10-year guarantee. Its listed coverage includes North and East London locations such as Southgate, Chingford, Walthamstow, Ilford, Barking, Greenwich and Lewisham.
