ALWAYS Use someone you have been satisfied with in the past if you can, even if you have to wait longer than you would like for their services
NEXT BEST If possible use a company on the recommendation of a friend. Then you have the peace of mind of knowing they were satisfied with the work carried out for them.
ASK Friends groups on social media.
NEVER Use doorstep callers. Reputable companies do not turn up on your doorstep unannounced.
DO NOT Use anyone you don't have a contact address for in case you have a problem. A phone number is not enough to trace someone.
BE WARY Of special offers (are they genuine?) & wild claims (is it possible?)
ALWAYS USE Common Sense. Look at the standard of advert, years of experience, price and time it takes to complete the work, don't be afraid to ask questions.
