Full window replacement systems vary from manufacturer to manufacturer.  Marvin Window’s system using a Kynar jamb extension is a nice way to provide a clean and maintenance free exterior application.

In the photo on the right, the old window has been completely removed and a new Marvin full replacement window has been installed in the opening.  Note how the minimally expanding foam fills the entire cavity between the window frame and the rough opening.  Nothing can get though the gap – not wind, not water nor bugs.

But to cap it off, literally, Marvin has a clean system that snaps into the exterior window frame and butts against the existing brick opening.  This jamb extension using Marvin’s extremely durable extruded aluminum is substantially stronger than roll-form aluminum and features a protective 70% Kynar® 500 paint finish for superior resistance to fading and chalking.  Kynar, in particular resists fading and comes in 19 colors.

I am very impressed with this replacement system from Marvin and encourage anyone who is ready to consider new windows to look at Marvin.

“Just do it!” – a notable trademark of Nike that catches everyones eye.  I always wanted to make tee-shirts for my employees that said, “Just do it right!”  I paused for fear of trademark infringement, but still like the message.  I am confident that our team thinks that way, even though we don’t have the tee-shirts.

In the case of replacing a dormer window, it would have been easy to plug the new window in and consider the job done, but that would have been a huge disservice to our client.  The trim around the window was rotting and the siding was all but deteriorated.  I wonder how much water was getting into the home through the trim and siding alone.

We chose to remove everything, down to the exterior sheathing so we could observe the flashing and ensure that the dormers were flashed, sealed and water and air infiltration were managed properly.

The new finished product assures our client of a weather-proof installation that will stand the test of time.  We used synthetic exterior millwork, 70% Kynar 500® cladding on the Marvin Windows and a cement based siding on the sides of the dormer. The Kynar cladding from Marvin Windows and Doors comes with a 20 year warranty.  The synthetic trim and cement siding takes paint well and resists rot and deterioration for years to come.  The future maintenance requirements will be minimal.

Always look at the bigger picture and don’t cut corners on a significant investment such as window replacements.  Find a contractor that is familiar with the best products and procedures in your marketplace.  Evaluating all the issues for a client up front is a detail that can’t be overlooked.

Take a walk around the outside of your home this weekend.  This is a great time of the year to replace your old rotting windows.  It’s pretty easy to find the problems.

Look for peeling paint in the corners of the windows, obviously rotted wood parts and glass that has clouded over.  Glass that is clouded indicates that the seal has failed , a common issue with older windows.

One of the more interesting problems that occurs with windows is the result of the a carpenter bee commonly known as the wood borer.  Carpenter bees don’t actually eat the wood but bore holes for their nests.  The resulting holes are surprisingly large.  If cracks and holes are not filled, water can enter these holes and freeze in the wood. The expansion properties of the ice will cause further deterioration of the wood parts and the window will be in much worse shape the following spring.  If your windows look like any in these photos, they should probably be replaced altogether.

A few minutes of observation now will identify these problems before you are faced with dealing with them in the cold of winter.

If you are considering replacing the windows and exterior doors in your home, make sure you carefully evaluate your investment.  New windows and doors can be one of the most significant energy efficiency improvements one can make in a home.  The current tax credits add additional incentive and the investment can arguably break even in a reasonable number of years.  All this plus the additional comfort you notice in your home on a daily basis is enough to pick up the phone and call one of the many window replacement firms in the Washington, D.C. market.

Many window companies offer replacement kits, sash packs or inserts.  These solutions may appear to be good values and offer less disturbance to the existing interior spaces but consider what you are missing.  If one leaves the old existing frame in the opening and just installs new sashes with a frame insert kit, think again about the quality and true energy efficiency of your investment.  A tremendous amount of air enters around the frame of a window, especially in older homes.  There is very little insulation, if any, around older windows and air and water can still enter the home even with a new sash or insert kit.

Look at the adjacent photos of existing windows in a home.  There is significant mold, water intrusion, air penetrating the home and even bug and ant nests.  If one used insert windows or a sash kit, these conditions would still be there unbeknownst to the home owner.  After a significant investment in new windows, wouldn’t you be shocked and disappointed to know these issues were still there!

There is really only one way to properly replace a window.  Replace the entire window and frame – PERIOD.  No inserts, no sash packs, no cutting corners to save anything existing.

Compare this photo of a properly flashed and weatherized new Marvin window and frame to those examples above.  Vikor adhesive flashing is wrapped from the outside sheathing into the opening preventing water intrusion.  Expansive foam has been injected between the window jamb and rough opening. This foam completely blocks air and pests from invading the home.  The foam will be trimmed flush with the window frame prior to the finished trim installation.

Which would you want in your home?  A sash pack or insert window kit which does not address significant existing issues around the window frame or a weather-tight, pest free installation that protects your investment?  The answer is pretty clear to me.

Next in our series of possible bathroom design options we look at adding a couple of feet to the back of the room and creating a shed dormer.  We want to manage costs so the expansion will be minimal but still develop the necessary space.  The sketch on the right is the same starting point we have for our other design options.  Now let’s see what happens with a few extra square feet positioned in the right place.

We will incorporate a tub, full shower, two vanities and a toilet compartment in this expansion.  The tub is generously sized with ample room on the deck for towel storage and decorations.  The shower has a large seat and potential for multiple heads and there is room for a private area for the water closet. Having his and her vanities makes sense for many couples.  The complement of quality cabinets on either side of the room, such as the WoodMode cabinets we feature, not only allows symmetry in the space but creates a focal point to the tub and window above.  The added window could be the most valuable component.  Large amounts of natural light flowing in the bathroom through a round or elliptical transom makes the room feel more connected to the outside.  The ambient light in a room often negates the need for illuminated lights.  Finally, look at the closets.  They have more than doubled – something every family could use!

So now you have three functional options to the standard bathroom in the Washington, DC, metropolitan area.  Each one has different priorities but none come at significant expense because they are designed and constructed in a logical and practical manner.  With these designs you can bring your home from the 1940’s quickly into optimum design standards for your lifestyle today.

It must be hard for a consumer to decide how to select replacement windows or windows for a new home.  How do you start, where do you start and who do you trust for such an important investment?  All the manufacturers claim high efficiency glass, tax incentives and new and improved technologies.  In my career at Natelli Homes, which is going on 25 years in residential construction, the window and door industry has grown and improved the most.  The standards for all the major manufacturers are so much improved that I would venture to state that there are arguable financial and performance benefits to replacing windows that are only 10 years old.

Windows and exterior doors are the biggest contributors to heat and energy loss in a home.  People notice it more in the winter when we can feel the cold spots and drafts around windows and doors, but imagine how much is also lost in the summer when we are not quite as sensitive.  Poor performing windows and exterior doors contribute to an immeasurable amount of energy loss in our world.

Again, where does one start?  You might start with the U-value of a window which is a measurement of 4 combined ways windows lose heat.  This is a standard by which a homeowner can evaluate the performance of manufacturers on an even playing field.  Simply put, the U-value of a window combines the heat loss of a window through (1) radiation, (2) convection, (3) air leakage and (4) conduction.  The lower the U-value the better performing the window is.
