We bought replacememt windows: 4 sash, and 2 casement. The four sash windows leak air. The sale rep who sold the whole package to us knew how bad the wind was on our farm (we told him) but sold us these sash windows anyway. Five "adjustment" visits later, now one of them is leaking rain too. RBA came out and has offered to replace all the sash windows with casements (the two have performed well). Do I dare stay with them or should I demand a refund? This company is weird. The installers and service people are wonderful--unfailingly professional and polite, but the marketing and sales are... liars and worse.
