We had a leaky second story master bedroom window that was going on for about 5 years until we discovered the problem. Nick from A Plus windows and doors saw the issues right away and his team fixed it. Since then there have been some heavy thunderstorms and we have not seen any problems with water intruding into the bedroom or dripping down to the first floor like before.
We also had a slightly crooked front door, very heavy. The same team (Murab and Sura), aligned it very well and now it is easy to open and close.
Lastly, we have heavy sliding patio doors which they adjusted and lubricated so that they slide more easily.
Thanks, Guys! Very much appreciated.
Also, we like that they aren't there to sell you a whole new set of windows, if it can be fixed in a cost-effective way., though they have that facility if you need. The only minor issue we found was scheduling an appointment with them, which may take a bit of patience, but worth it in the end.
