Don’t ever hurry into selecting a builder, as it could be one of the more harmful decisions you ever make. Soon after you understand what you want done to your property or place of work, generate the drawings done, and then go about getting a contractor to do the job.
Having accurate drawings will guarantee you generate an suitable estimate, also it should illustrate any ‘extras’ before the they arise.
Something you can do is project manage on your own (if you know what you are doing, or alternatively get a contractor who will give you a price for all the works. This is often the advisable method as it avoids expensive hold ups where you could be paying a tradesman to hold off. Good trades people do cost more, but they make up for this in so many methods.
There are masses of individual techniques to generate prices, but the most typical is to tender it., that is to say, supply the contractor the specifications sheets, and let him bring back to you with a price and some conditions or proposals. The least expensive is not always the best, keep this in mind.
Also query if this is a quotation or an estimate, don’t think they are one and the same, as a quotation is a fixed cost for set job, while an estimate is a rough guide and can be changed at any time.
Always query for references of satisfied customers, and drive around to guarantee the task was actually sorted out, don’t just take their word for it, as it is easy to get a friend to vouch for them and sing their praises.
Arrive at sure you have a solid signed agreement prior to start of work, and agree any stage fees in advance, together with the juncture stage that triggers them.
And finally, necessarily speak to your builder in detail, generate his advice, get a feel for them, but most of all, remember the old adage of, ‘if it sounds too good to be true, it probably is’.--[link]
