Saving Builders Time, Money, & Headaches

We know how frustrating it can be to work with a vendor that forgets to place orders, orders items with the wrong specs, or doesn’t understand how simple measurements are measured correctly. These issues stop the job and increases timeline and prevent other scopes from starting their work. If you’re a builder that doesn’t cut corners, doesn’t sacrifice workmanship, and has high integrity, we want to help you succeed.

Warranty service claims are supported through the purchasing dealer. It is strongly advisable to know the following information:

  • Manufacturer
  • Order number
  • Year of purchase.

If you do not have this information, there is a “bug” in the corner of the glass that is a unique identifier for any window and door. Checking the hardware for manufacturer name is another technique we recommend.

Having a record of your Manufacturer’s warranty is extremely important, so that the terms of warranty are followed. Oftentimes, at the 10 or 20 year mark, a warranty for materials ONLY is expired. If the product is out of warranty, we can help you determine if the best recourse is to purchase a new window or door, or if you need a company that specializes in servicing and replacing parts for window and door hardware.

If we are not the original dealer who sold your product, our hands are tied for warranty service claims as we do not have a record of your order. Also, if you are beyond the warranty period, the manufacturer will not provide materials.

We offer several product lines from over a dozen manufacturers for new construction (nail-fin or block frame) and new retrofit (flange, casing or zbar) replacement windows. With new retrofit windows, the existing window or door frame stays intact and there is no penetration of the existing waterproofing; the new retrofit window is slide into the existing opening and the retrofit flange covers the old frame. This is a much faster and economical solution when compared to new construction. The tradeoff is you loose daylight opening and have a thicker frame build up to the exterior and interior.

We do offer several product lines with short lead-time. Call for more information.

Regardless of how you identify yourself (builder, homeowner, developer, architect, designer), we use these markers to facilitate our process:

  1. Understand your primary goal and timeline for buying new windows and doors.
  2. Review and select the product for budgeting (pricing and lead-time) purposes.
  3. Approve Quote, understand warranty, and initiate final review of specification sheets, shop drawings (if applicable), finishes and finish details with the building and design team and the homeowner.
  4. Approve contract and submit deposit payment to initiate the order approval process with the factory.
  5. Begin delivery coordination with the installation team and mark the ETA of the materials.
  6. Check in with the factory and the jobsite regarding jobsite readiness.
  7. Send an invoice for final payment and begin delivery coordination two weeks prior to the ETA.
  8. Receive the delivery, inspect the product, and schedule a check in of an unwrapped product follow up.
  9. Additionally requested post-sale support services.

On average, proposals take 1-2 weeks. This depends on scope, if plans are present, and if special factory approval is needed. If drawings are required as part of the order process, we need a deposit and on average 2-4 weeks to generate drawings.

With an engaged customer, the sales process typically takes 2 weeks to review and revise the window and door package, as there can be several parties participating in the review process – homeowner, builder, and architect.
