Transforming Your Dream Into Reality

“D2 Build is the best contractor I have ever hired for a job. D2 designed and built an entire home renovation for my current home. I give D2 the highest possible recommendation and have already passed them onto many friends and family for all types of projects.”

They are knowledgeable, experienced, know what to prioritize, and where your money is best spent. Most of all, they have incredible integrity.”

FREQUENTLY ASKED QUESTIONS

Why should I replace my old windows or doors?

Upgrading windows and doors improves insulation, eliminates drafts, and reduces energy bills. Modern options also cut outside noise, enhance security with stronger locks, and operate smoothly. Plus, new designs boost curb appeal, making your home more comfortable, secure, and attractive while adding long-term value.

How do I know if my windows or doors need to be replaced?

Signs include drafts, condensation between panes, or difficulty opening and locking. Visible decay, cracked glass, or water damage also signal replacement needs. Even if undamaged, windows older than 20–30 years perform poorly compared to modern models. Our team can assess and recommend upgrades suited to your home.

Are there rebates or incentives for installing energy-efficient windows in Toronto?

Yes—programs like the Canada Greener Homes grant and Ontario’s Home Efficiency Rebate Plus offer up to $325 per unit. Ontario’s new Home Renovation Savings Program covers up to 30% of costs. D2 Build helps you navigate audits, applications, and installation so you maximize savings while lowering monthly energy bills.

Do I need a permit to replace or add new windows or doors?

Basic replacements with no size changes usually don’t require permits. Enlarging openings, adding windows, or converting to doors does. D2 Build handles permits, drawings, and inspections when needed, ensuring compliance with Toronto’s building codes. If no permit is necessary, we’ll confirm and proceed with a smooth, legal installation.

How long does a window or door installation take?

Most single units take a few hours; a typical home (8–12 windows) takes 1–2 days. Larger or custom projects may extend up to a week. We install one opening at a time to limit disruption and weather exposure. Our team keeps projects on schedule, cleans daily, and ensures quality finishing.
