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? If you are a business owner, offering Aspray’s service to your clients could enhance your chance to gain new customers, retain existing customers and add an extra income stream to your business whilst giving you an edge over your competitors. Aspray (Luton) is a trading name of (Maynard’s Property Services). Aspray Limited is authorised and regulated by the Financial Conduct Authority

John and the team did an outstanding job. It was easy to work with John and he was very knowledgeable, and provided very sensible advice. Other people quoted work which was over-the-top or wouldn't have solved the problem but John got right to the issue in a no-nonsense way. Quality of the work undertaken was very good, considering the age of the building and complexity. Would recommend.
