Glass realignment utilizing Toe Hill method and reset of the aluminium door
The guys did an outstanding job fixing my aluminium balcony door which was sagging due to the weight. The job turned out far more challenging than anticipated but the guys found a solution and carried out the work with care and great attention to detail. The quality of the repair was excellent and the door is now working as it should. I would have no hesitation in recommending Thermalseal UK Ltd and would definitely use their services again.Verified reviewerJob location: E16RLouise L10 UPVC Windows Repair
