A window that used to feel fine and now feels cold isn't getting old in some vague, general way. Something specific changed. The seal between the panes of glass can fail, letting the insulating gas escape and the glass lose its ability to hold temperature, often showing up as fog or condensation trapped between the panes. The frame itself can shift slightly over years of expansion and contraction through Minnesota's temperature swings, opening small gaps that let air through around the sash. Or the window simply wasn't that efficient to begin with, especially if it's an older single pane unit or an early double pane from a few decades ago.
At Twin Cities Exteriors, we will sit down and walk you through the frame and glass conversation based on your specific room. Vinyl and fiberglass perform differently across Minnesota's temperature range, and double pane versus triple pane glass makes a real difference in colder rooms and north facing exposures. Twin Cities Exteriors walks through what fits each space, to make sure you keep the cold air out, and the memories in.

An evaluation of the frame, not just the glass. Before recommending insert or full frame replacement, Twin Cities Exteriors checks whether the existing frame is square, sound, and free of rot or water damage. That evaluation determines which approach actually solves the problem.
Careful removal that protects the opening. Old windows are removed without damaging the surrounding frame, siding, or interior trim more than necessary, especially important when an insert approach depends on that frame staying intact.
Installation sealed and flashed properly. Whether it's an insert or full frame replacement, the opening is sealed and flashed during installation so the improvement isn't undone by a gap around the new unit.
A finished look inside and out. Interior and exterior trim get reset and finished as part of the project, so the new windows look installed, not patched in.
Condensation between the panes of a window, as opposed to condensation on the inside surface of the glass, is one of the clearest signs that a seal has failed and the insulating gas between the panes is gone. Homeowners who've been through a Minnesota winter with a failed seal tend to notice it fastest in north facing rooms, where the cold is most persistent and a failed window stands out from the others nearby. Catching that before the next heating season starts is less about urgency and more about not paying to heat a room that's losing the battle through the glass.
Insert Window Replacement. A new window unit installed into an existing frame that's still square and structurally sound, without disturbing surrounding trim or siding. This is the faster, less invasive option when the frame allows for it.
Full Frame Window Replacement. When the existing frame has shifted, rotted, or is no longer sound, the entire frame is removed and replaced. This addresses the underlying problem directly rather than building a new window into a compromised opening.
Energy Efficient Glass Upgrades. Double pane with low e coating provides a solid baseline for most rooms, while triple pane adds a meaningful difference in colder rooms, north facing exposures, or spaces near outside noise.
Egress and Code Compliant Windows. Basement and bedroom additions or remodels often require windows that meet specific egress and energy code requirements, and Twin Cities Exteriors handles that as part of broader remodeling and addition projects.
One Crew Handles The Whole Exterior: Roofing, siding, windows, gutters, and decks all run through the same company. There is no handoff to a separate siding subcontractor or a separate gutter installer who never saw the roof plans. The same people who tore off the old roof know exactly what's happening at every flashing point, every transition, and every connection to the rest of the house.
11 Years Of Roofs Built To Last: Since 2015, Twin Cities Exteriors has been working on roofs that have to survive freeze thaw cycles, ice dams, and hail seasons that catch a lot of homeowners off guard. That's eleven years of seeing which materials and installation details actually hold up here, not just which ones look good on a spec sheet.
We Address Your Home As One System: Because the same team handles roofing through interior remodeling, the recommendation a homeowner gets isn't limited to "you need a new roof." If the real issue is ventilation, or a gutter pitch problem, or flashing where the siding meets the roofline, that gets identified and explained as part of the same conversation.
Colin walks your property with you personally and inspects every layer of your exterior: the decking, the siding, the flashing at every intersection, and the overall surface condition. He is looking for what your home actually needs, and to better understand what you're looking to achieve. You get a clear, honest assessment before any paperwork is brought to the table.
You receive a written proposal that specifies materials by product name, describes the scope of work at every layer, and gives you a timeline you can plan around. No vague line items and no placeholder language. If there is something that could affect the price once work begins, it is disclosed before you sign.
Our professional crew arrives with a dumpster or trailer, begins with a full decking inspection before any new material goes down, and photographs the completed stages as they work. Magnetic nail sweeps run at the end of the day. For roof replacements, the job is completed same day so your home is never left exposed overnight.
Before we leave, we do a final walkthrough with each homeowner so no question goes unanswered. You know what was done, what products were installed, and what your warranty covers. From that point forward, if anything comes up, you call the same number you called on day one.
If the existing frame is square, solid, and free of rot, an insert replacement installs a new window into that frame without disturbing the surrounding trim or siding. If the frame itself has shifted, rotted, or is no longer structurally sound, a full frame replacement addresses the frame directly. An evaluation of the frame's condition determines which approach actually fixes the problem.
It means the seal between the layers of glass has failed and the insulating gas that was between them has escaped. This is different from condensation on the inside surface of the glass, which is more often related to indoor humidity. Once the seal fails, the window's insulating performance drops significantly, even if the frame itself is still in good shape.
Many window replacement projects are completed in a day or two depending on the number of windows being replaced and whether any unexpected issues, like frame damage, are discovered once the old window is removed.
Vinyl frames offer strong value, low maintenance, and good energy efficiency across Minnesota's temperature range. Fiberglass frames cost more but expand and contract less with temperature changes, which reduces stress on seals over time and tends to matter most on larger windows or particularly harsh exposures.
