Windows Estimating Services

Window estimating is a technique that involves counting each window in a project, recording the size, material and performance allotted for each window, and then providing this information to the supplier for a more accurate quote.

Our takeoffs will reference window schedules and elevations in order to count units by type, size and material and include glazing type, performance ratings, if applicable.

These quantities are not only a critical part of the actual bid but also directly contribute to material ordering and scheduling after the project has been awarded, as an incorrect windows takeoff can cause issues long after the winning bid.

All window quantity takeoff assignments start with a thorough examination of the drawings and specifications, and then are completed by taking quantities by the categories that are most important to pricing accurately.

After the quantity is measured, a second estimator reads the takeoff to check for quantity mistakes and/or scope gaps before the bid is priced, before the mistake ever affects your bid.

Window performance requirements (thermal, impact resistance and acoustic) differ depending on the climate zone and code jurisdiction, and we verify these against the window schedule, not assume any standard window that would be found on an average residence. In commercial projects, in particular, there may be different types of windows on the same elevation, so it is important to monitor them by the location.

Standard sized vinyl or wood windows generally are used in residential window estimating, while commercial window estimating may encompass larger storefront windows, custom aluminum window systems and higher performing windows.

Because Forte’s estimators have a foundation in the trade, specialty subcontractors bidding windows choose Forte. That industry information can be very useful to us in picking up scope information that may not have been obvious to a generalist estimator – safeguarding your margin before you even offer them a number.

We also provide flexible pricing for windows estimating, whether it’s a single window price or a monthly retainer for subcontractors who bid this scope of work on a regular basis, and want a consistent and reliable estimating partner.
