Get your new window/ door opening permit drawings done right!

Did you know unclear new window/ door opening permit drawings can cost you hundreds of thousands or even more? Getting drawing done right not only save time and also money during construction. A lot of time, client misunderstood the importance of drawings and many think the permit drawings is only a document to get you a building permit. This kind of thinking is absolutely wrong, a set of good drawings not only can provide cost-saving that meet your budget and also able to convey the correct idea or intention to your contractor. Good drawings also help collaborate with all consultants to ensure your permit and construction process goes as smoothly as possible.

Deck and Sliding Door Plans Permit Works proved to be excellent to work with. Communication was always clear, and they were diligent and timely when changes to the plans needed to be made based on feedback from the city.
