If your spending your hard earned , it needs to be done right, but regardless of who does it, it grinds me that these great Co’s never tell you the true facts, when it is “done correct” thats not the end of it and it is all done and forget about her ,she will last for ever, you are entering a process of managing it , its “needs” to be checked every 12 months ,say MOT time, get under there and deep check, the box sections “need” to be topped up every 3 years, so you are staying on top of it , just like you would with the paint on top, any one that says " done in a day or two" just walk away, its a deep process to be done correct and you would be wasting your time and cash with flash overs.
Who ever you get it done by , you want pictures, shed loads for proof and for further down the line, a lot of these Co’s do the talk and will take your money with out a blink.
