Most of the housing here is small-farm houses and bungalows in drumlin country, hedged boundaries and working yards. The local condition that shapes the job is damp, cool and consistently wet, with wind funnelled between drumlins, which is why wind funnelled between the drumlins hits individual elevations hard while the rest of the house sits sheltered, so it is common to need one side of a house done and not the others.

Ask for a measured survey before any price, and get the quote in writing afterwards.

Monaghan town is in Monaghan, where T&Aglass is registered, so yes. They work across Monaghan town, Carrickmacross, Castleblayney and out to Ballybay. Whether they will travel to a specific townland is worth asking directly, particularly for a smaller job.

No Google rating is showing for T&Aglass at the moment. That can mean nobody has left one, or that fewer than three people have, because we hold a rating back below that rather than presenting one review as a score. It says nothing about the quality of their work. Ask them for two addresses locally where they have done the same job, and go and look at them.
