Patrick did a great job in brickwork (opening our kitchen window aperture), pointing and skimming. He went along our tight schedule and provided helpful advice and a fair price. I strongly commend his work. Thank you Pat!

I take care of managing your property damage insurance claim so you can carry on with everyday life or running your business. Your home is your sanctuary. Fire, flood, water damage, storms, impact or criminal damage can threaten that. If the worst happens, I can negotiate a fair settlement from your insurer and then return your property to its original condition. There is no charge to policyholders for the Aspray service provided Aspray can appoint and project manage the contractors who carry out the repair works, as Aspray is paid by the insurance company for any repair or reinstatement works they complete. Please note, any excess stated within your policy wording, will still apply.In the event you need to make a claim, wouldn’t you rather have one point of contact looking after your interests rather than dealing with various different parties?
