Why You Need a Contract
A detailed contract sets clear expectations for both you and your contractor. It outlines the scope of work, specifies materials and installation methods, and provides legal protection should something go wrong. Without a written agreement, you risk misunderstandings about price, schedule and quality.
Houston's permitting requirements and building codes add another layer of complexity. A good contract clarifies who is responsible for securing permits and documents any warranties. It also lays out how changes will be handled, so there are no surprises.
Essential Elements
Before signing, make sure your window contract includes the following:
- Project scope: A list of each window or door being replaced, including sizes, rooms and any specialty shapes.
- Product details: Brand, material (composite, vinyl, fiberglass), glass package, color, grid pattern and hardware. Note if windows are impact-rated for hurricanes.
- Installation method: Full-frame vs pocket-fit. This is the single biggest quality variable. Make sure the contract spells out which one you're paying for. Read about the difference on our window installation page.
- Timeline and schedule: Start and completion dates, lead times for ordering custom windows and how weather delays are managed.
- Payment Terms: Clear steps for payment. We require 50% down to order your custom windows, with the remaining balance due only when the job is complete. If you need to spread the cost out, ask the contractor about financing at signing.
- Warranty: Length and coverage of manufacturer's frame and glass warranty plus the installer's labor warranty.
- Cleanup and disposal: Confirmation that old windows, debris and trim will be removed and the job site left tidy.
Financial Terms & Payment Schedule
Never pay the total amount up front. A 50% deposit is required to initiate the custom manufacturing of your windows. Full payment of the remaining 50% balance is contingent on completion of the installation. Insist that the contract spells out the total price, deposit amount, and final payment due after you're satisfied with the job. It should also state how change orders are priced and approved.
Budget for surprises. Unseen rot or structural repairs may not surface until old windows are removed. A contingency line item helps avoid disputes if additional work is needed.
Signs You Need an Assessment
Not sure whether you need new windows yet? Look out for these red flags:
- Drafts or temperature swings despite closed windows.
- Rotting or decaying frames - especially on wood windows.
- Condensation between panes or fogging glass.
- Difficulty opening or closing windows or doors.
- Increasing energy bills with no other explanation.
- Outside noise infiltration that seems louder than before.
- Visible cracks, broken locks or security concerns.
- Fading furniture or carpets from UV exposure.
- Windows older than 20 years with original single-pane glass.

Frequently Asked Questions
While Texas does not mandate a written contract for small home improvements, a detailed agreement protects both parties, outlines scope and pricing, and provides a paper trail if disputes arise.
Standard payment terms are a 50% deposit at signing to begin custom manufacturing, with the remaining 50% balance due upon completion of the installation.
