Sealed Tight Against Winter Drafts

RLF Contracting llc installs and replaces windows and doors for homeowners in Woodstock, Illinois.

You feel cold air leaking around window frames in January or notice condensation forming between panes during overnight temperature drops. RLF Contracting llc replaces outdated windows and doors in Woodstock homes with properly sealed units that reduce drafts, lower heating costs, and improve security. New installations are shimmed, leveled, and insulated to perform through freeze-thaw cycles common in northern Illinois.

Each installation starts with accurate measurements of existing rough openings. Old units are removed, and framing is inspected for rot or damage before new windows or doors are set. You will notice tighter seals, smoother operation, and less noise from outside traffic or wind. Caulking and weatherstripping are applied to prevent air infiltration at sill plates and jambs.

What Changes After New Windows Go In

Your installation begins with removal of interior trim and exterior casing in Woodstock. The old window or door is taken out, and the rough opening is checked for level and square. New units are set into place, shimmed at multiple points, and fastened through the nailing flange or frame.

After installation, you will see clean sight lines, no gaps between the frame and wall, and smooth operation of sashes or door panels. Locks engage fully, and weatherstripping makes contact around the entire perimeter. Interior temperature becomes more consistent, and you use less energy to maintain comfort during cold months.

Insulation is added around the frame to fill voids, and exterior trim is reinstalled or replaced to match your home's siding. Interior casings are caulked and painted if needed. RLF Contracting llc works with common home styles found throughout McHenry County and adjusts installation methods based on siding type and wall construction.

How do I know when windows need to be replaced?
You will notice drafts near the frame, condensation between panes, difficulty opening or closing the sash, or visible rot around the sill. Any of these signs indicate the unit is no longer sealing properly and should be replaced.

What type of door improves security the most?
A steel or fiberglass door with a deadbolt and reinforced strike plate offers the most resistance to forced entry. RLF Contracting llc installs doors with multi-point locking systems when security is a priority.

What happens if the framing around the opening is rotted?
Damaged wood is cut out and replaced with treated lumber before the new unit is installed. This ensures the window or door will be supported properly and sealed against future moisture intrusion.

Why do some windows fog up between the panes?
Fogging happens when the seal between double-pane glass fails and moisture enters the space. Once the seal breaks, the insulating gas escapes and the unit loses its energy efficiency. Replacement is the only fix.
