- Serving Lakewood, Crystal Lake, Schaumburg & More!
- Work with the Premier Roofing Company
Homeowners in Lakewood, Crystal Lake, and Huntley trust us to expand their homes without disrupting daily life. We handle permits, structural work, and finish carpentry under one roof.
Every addition project starts with a site assessment and a clear plan before any framing goes up. You stay informed at every phase.
A solid addition starts below grade. We dig footings to the required frost depth for Illinois — typically 42 inches. The framing ties directly into your existing structure so the addition feels like part of the original home. We use lumber grades and fastener schedules that pass McHenry County inspections. Crystal Lake and Huntley projects follow the same structural standards.
The addition should look like it was always there. We match siding profile, color, and trim detail to your existing exterior. Rooflines get tied in properly to prevent ice dam buildup during Illinois winters. Window placement and sizing balance natural light with wall insulation values. We source materials that hold up through freeze-thaw cycles common in McHenry County.
A sunroom gives you usable space for most of the year in our climate. We frame with thermally broken aluminum or wood, depending on your heating plan. Insulated glass panels handle the temperature swings between Lakewood summers and winters. We connect the sunroom to your existing HVAC or install a dedicated mini-split unit.
We start with a free site visit and scope conversation. After permits are approved, our crew mobilizes and works in a clear sequence: demo, foundation, framing, mechanical rough-ins, insulation, drywall, and finish. We keep disruption to the occupied part of your home to a minimum throughout. Final walkthrough happens before we close the job and clear the site.
