Windows built for Houston heat, installed by Houstonians.
Meet Evergreen Platinum — our flagship replacement window. Custom-built to every opening in your home, independently certified for performance, and covered by a double lifetime transferable warranty on materials and labor.
What your windows aren’t telling you.
Failing windows rarely announce themselves. They show up as a room that never cools, a bill that keeps climbing, and a sill that gives a little when you press on it. By the time you notice, the damage has usually moved past the window and into the wall.

Evergreen Platinum. Tested. Trusted. Proven.
Evergreen Platinum is the only replacement window DC Pines installs. Built to our specification, tested by independent third-party laboratories, and manufactured on a line with nearly eight decades of history behind it — then installed under our project management and warrantied by DC Pines, not by a factory in another state.
No good-better-best ladder. No upsell waiting in the driveway. One window, specified properly the first time.

Where the difference actually lives.
Every window looks the same in a brochure. Here is what you cannot see from the curb — the two engineering choices that separate a window that lasts thirty years from one that fogs in seven.

The difference is in the space.
Argon is about twice as dense as oxygen, so it slows heat transfer between the panes of glass. It is a colorless, odorless, inert gas — the physics do the work.
A typical insulated glass unit is filled to roughly 30% argon and 70% air, which means only the bottom third of the cavity is doing real work. Evergreen Platinum is filled to 100%, corner to corner.
On a Houston south-facing wall in August, that difference shows up on your HVAC run-time — and on the summer bill it produces.

The hidden upgrade that keeps your view clear.
A patented polycarbonate warm-edge spacer with zero metal content — so there is no thermal bridge at the edge of the glass.
Metal spacers transfer heat and cold, expand and contract with every day and night in Texas, and put stress on the seal until the unit fogs. This one does not. It is the single most common reason older windows fail early, and the single easiest thing to get right.
U.S. Patent 6,581,341. It is on the spec sheet. Ask any window company for theirs.
Windows we’ve put in this year.
Every opening measured, every unit custom-built, every install protected inside and out. A small selection from recent DC Pines projects across greater Houston.








Eight decisions that determine whether a window lasts.
Most replacement windows look identical from six feet away. The difference lives in the parts you never see — and on the Gulf Coast, those are the parts that fail first.
TimberLock™ Spacer
Patented polycarbonate warm-edge spacer with zero metal content. No thermal bridge at the edge of the glass, no expansion stress on the seal.
100% Argon Fill
Argon is about twice as dense as oxygen, so it slows heat transfer between panes. Filled to 100% — not the industry-typical 30%.
Evergreen Silver Low-E
Microscopic layers of silver reflect unwanted heat while visible light passes through. SHGC 0.23 for fewer hot spots and less fading.
Thermacell® Insulation
Foam engineered into the frame chambers at the factory — not stuffed in afterward. Reduces heat transfer, dampens noise, adds rigidity.
Fusion-Welded Corners
Fused into one continuous piece rather than screwed or crimped. Mechanically fastened corners loosen and leak. Ours don’t.
Reinforced Meeting Rails
Internal metal support keeps wide units from bowing or warping — so the locks keep engaging and the seal keeps sealing years from now.
Enhanced Strength Glass
Upgraded double-pane package rated to DP 50 design pressure — engineered for storm season, high wind loads, and the occasional stray baseball.
TitanShield™ Vinyl
100% virgin vinyl with premium UV protection. No regrind, no recycled filler — the difference on a south-facing Texas wall.
Twelve ways to open a wall.
Because every window is built to its own opening, you can mix styles across the house without a stock-size compromise. Grids can differ from the front elevation to the back.
Four steps. No all-day sales pitch.
Free in-home estimate
We measure every opening, inspect the condition around it, and put the actual window in your hands.
Written proposal
Priced per opening with sizes, styles and options spelled out. Take it and think as long as you like.
Custom manufacturing
Your windows are built to your measurements. Progress is posted in the customer portal as it happens.
Install & walkthrough
Your install team protects the space, sets every window, cleans up, and walks the house with you.
Double lifetime transferable. Materials and labor.
Most window warranties cover only the part and leave you paying someone to install it. Evergreen Platinum covers both — the insulated glass unit, glass breakage (including accidental), hardware, screens, materials, and labor.
It transfers once to the next owner when you sell the house. We hand you the full warranty document at the estimate so you can read the terms before you commit to anything.
