Your Local, Award Winning Home Replacement Window Company serving Houston, Dallas, Austin.

Over the last 35 years, we at Allied have found there are several reasons homeowners to have replacement windows installed.  Obviously, energy efficiency comes to mind, and it is probably the number one reason homeowners replace their windows.  However, we often hear homeowners say something like, “I am very glad my home will be much more energy efficient with these new windows, but I have other reasons I want to replace my old windows…”  This is what we hear:

Energy efficiency – Allied’s windows will save you money 24/7.  What else works for your pocketbook non-stop?  

Comfort level – Though this is related to energy efficiency, it is different.  Your home will no longer have hot and cold spots; you will enjoy uniform comfort.  Many happy customers wonder why they waited so long.

Beauty – Allied’s windows give beauty to both the exterior and interior of your home.  Your home will be more attractive. You will enjoy looking AT your windows, not just THROUGH them.

Ease of operation – Many, if not most, old windows are difficult to operate; some won’t open at all.

Ease of cleaning – The tilt-in features make cleaning a joy rather than a chore.

Noise reduction – Many homeowners marvel, “I thought I lived in a quiet neighborhood, but now my home is so much quieter.  I didn’t realize there were so many distractions outside.”

Reduction of dust / pollen – Another great benefit.  Allied’s customers tell us their home doesn’t get as dusty as before.  Truly, old, leaky windows cause energy loss, but also dust gain! Additionally, those who suffer with allergies find our windows help keep out pollen and other allergens in our Texas climate.

Increase in resale value – Replacing your old windows increases both the value and desirability of your home, should you ever choose to sell.

Why We Use Andersen Windows

Allied Siding and Windows | Andersen Windows

Andersen 100 Series:   Full Fibrex Composite Windows 

Superior strength and performance with environmental responsibility.  The exclusive Anderson Fibrex composite material is composed of 40% reclaimed wood fiber by weight, most of which is reclaimed from the manufacturing process of Anderson wood windows.

Energy efficiency.  Anderson weather-resistant construction seals out drafts, wind, and water so well, you can relax in comfort whatever the weather. Plus, Fibrex material blocks thermal transfer nearly 700 times better than aluminum to help reduce heating and cooling costs.

Colors that last – including black & bronze.  Durable, factory-finished interiors and exteriors feature a premium matte finish that is not shiny like vinyl.  Plus, the replacement windows never need painting; they are fade resistant and will not flake, blister, or peel in any climate. The finish is 12 times thicker than that of a painted window, resulting in superior scratch-resistance so your windows will look beautiful for years to come.

400 Series/Woodright Replacement Window:  Real Wood Replacement Window with Clad Exteriors

Woodright Windows help replicate the look of traditional architecture. Their thick, sloped sills and historically accurate grill patterns bring out old world character to homes of all ages. To help match existing interiors when replacing or remodeling, order them in a variety of wood species, with custom extension jams, and with a range of hardware and grill options, including custom grills.
