Poor quality, no warranty, horrible man
This so called window company was used by the builder who wrecked our hopes of our dream house. After changing our plans to achieve a cheaper build, - we didn't know this and carried on paying as we thought we had a contract - he then employed this company to supply windows. The windows are all of very poor quality, scratched and damaged. They have only been in six years but in spite of telling a court that we had a warranty, Gerry O Sullivan refused to honour the warranty saying that it was only the builder that could use the warranty. One opener has not opened since we moved in and many bits and pieces are missing. He also had the nerve to lie to the court about the way we spoke to his staff - seems from other complaints that he has an aggressive way of speaking to customers who have already paid. Our front door has peeled from the first few weeks of being in place and the letter box and handle are steel while the threshold strip is brass - very tasteful! Seems that Gerry O Sullivan and Paul Varro are natural bedfellows as they find it impossible to do a decent job or to tell the truth. Don't touch either of them.
failed to honor our guarantee
KWS have failed to support & honor their 5 year Guarantee.Just after 3years .
We have had problem after problem with their product, We have contacted them time after time but we just get no response, The Director Gerry o Sullivan has spoken to us in a disgusting & appauling manner, It was just a shame he didnt speak to us like that before we placed our order.We spent a large amount of money with this company and we are appauled in the way we have been treated .
Looks like someone else knows o sullivan like the same way I know him. I see your very popular not, with a complaint on this site called crystal clear windows. tut tut!
We now have all are quotes and reports from all are companies, they all felt we have been let down with are so say 5 year guarantee, once again o sullivan has failed to make any attempt to contact us. trading standards are working with us over this matter. I guess zrn is in the same situation as we are. we have reported this company to the office of fair trading
Thank you for your comment ZRM, And for the votes.We have had the work inspected by many companies and they are appauled in the way O Sullivan has treated us as a family.We are still getting Quotes and will let you know the outcome. O Sullivan still has not got back to us.I have contacted the company that recommended them and they are deeply sorry.
The complaint has been investigated and resolved to the customer’s satisfaction.

With reference to trust mark, it maybe better to talk to them direct as I found out
If you have a issue with his new company you should create a new complaint on this site .
Yes stay away We reported this Gerry o sullivan to the Trading Standards
Ashbourne Windows have got their first review on www.yel.com and its a credible 1 star out of 5!
According to the trustmark website, KWS is trading as Ashbourne Windows, so rather than KWS going bust, they are just trading under different names. Does this mean anyone with KWS guarantees can still claim?
