Trouble free and friendly experience for a superb job from start to finish.
Tony (Installations) and his team were punctual, very courteous, knowledgeable, tidy, helpful and always happy, especially to ensure that our concerns as to how the installation of 34 units were to be undertaken were fully explained before the job commenced. On a job of this size with parts of the house dating back to the 18th century, challenges occurred which were fully assessed, discussed with resultant decisions implemented with the minimum of fuss with the whole overall job resulting in very little damage to the outside

Martindale windows and doors replaced the windows and doors in our property. Originally asked for them to come round based on reviews we had read online. Have to say from the initial appt with Tony who was brilliant from start to finish. The fitters were prompt and efficient. The whole process was great and simple. There were no questions pressure sales tactics just honest advise. Tony and the fitters Ryan and Cliff are a credit to the company.
