That’s a very good question, normally if it’s a larger job where the client has engaged an architect to do drawings it is advisable for them to prepare a scope of works for when it goes out to tender.
if this is something they don’t do then ask them to recommend a company to undertake this.
For smaller works, ie kitchen or bathroom rip out and install new I would suggest the following:-
Firstly take measurements of the said area.
Floor measurement, wall heights and measurements, size of windows and doors.
Further information what is the current substance? The substrate is what is underneath the tile/carpet. Is it concrete? Wood?
Take photographs of the area, and mark the measurements up.
This is called an existing plan.
Then sketch up a proposed plan,
for example if you have one central light fitting in the ceiling and you wanted 6 Down lighters mark them up on the photograph. Perhaps you’ve seen the tiles you like, for the floor so write it up something like:-
Floor Tiles 12m2 Porcelain Tile Madagascar Bianco 60x60cm
Put your list together, it also helps you with your materials budget.
It really helps the contractor and it’s also good for the client because it clearly shows visually how you want it to look.
Ive seen some really frustrated posts on this thread regarding trades not turning up, deposits being paid and slow works on site or in some cases no works done!!
I will state this now, and if it saves anyone of you handing money over to any cowboy trader it can only be good.
On absolutely no account never EVER a hand a deposit over Willy Nilly. If your contractor asks for a deposit, you should ALWAYS ask for a breakdown of what materials this is for. Also ask what the lead time is on these materials. Ensure that these materials are delivered directly to your home or the site. Never ever hand a penny over to secure a contractor who can “fit the works in 3 months down the line”. If you are handing over a large amount of funds for materials, ask for a VESTING CERTIFICATE! This effectively means that although the materials have been purchased by the contractor you are the legal owner of said goods.
You need to discuss payment plan and “milestones” when the milestones are reached in the works then payment is made.
Ultimately there will be extra works, always get the contractor to give you a quote as a separate item and confirmed in WRITING. If you are happy with the quote confirm it in writing if not then discuss it! NEVER EVER agree verbally to any extra works without a cost or not in writing.
Secondly do not and never hand over any money to Joe Bloggs Building on Facebook market place. Check your contractor out run a search on companies house, check they are vat registered, and in the case of a sole trader run a credit check. Ask for references and check them! Take those references up! Check the references and the address of the property, and for more major works they have completed check the council planning consent records on that property.
There are some amazing contractors, but there are also some appallingly shocking ones.
Thirdly don’t be swayed into engaging Billy Bullshit Builder because he’s got the gift of the gab. Remember what I wrote about running checks on contractors? Please use this as your mantra. Don’t be intimidated, stick to the script, and that way you can sort the wheat from the chaff.
