It depends on the project, for most projects you’ll receive a certain number of days we can guarantee the price for. Generally we can guarantee the price for a longer time if it’s mostly labour. When the quote has a lot of materials included, these can vary a lot in price (especially recently) so we won’t be able to guarantee the quote for too long.
An expired quote doesn’t mean that we can’t do the project, it just means that you’ll have to ask for a price update if you are interested in the quote again. Since we already discussed the project/took measurements, it takes just an email to get an updated quote.
