General Maintenance and Care

General Maintenance and Care

Mother Nature doesn't cut corners and neither do we. Select ponderosa pine. Heavy-duty cladding. Brawny hardware. Performance glazing. Precision joints. Solid to the core. While Hurd windows and doors are crafted to withstand the test of time, here are some basic steps you can take to make sure yours never bow to the elements.

Painting and Finishing - Exterior Finish - Wood Units

Do not paint weatherstrip, hardware and/or vinyl surfaces. Surfaces must be clean and dry before they are painted. Avoid painting during or immediately after extremely damp weather.

Most wood exterior units have a water-based factory-applied prime coat. Apply the finish coat(s) of paint within thirty (30) days after installation. Failure to finish the primed surface within this 30-day limit may require a new primer coat.

Use a high to medium-gloss exterior paint, preferably an alkyd base. Please note that some latex paints, especially high-gloss latex, can have a chemical reaction with the weatherstripping that will cause the sash to stick. And, although the glass bead is also vinyl in some cases, this bead can be painted as long as you use only pastel or other light colors. In certain climates, dark colors cause premature deterioration of the vinyl.

Lap-paint or finish approximately 1/16 inch onto both interior and exterior glass surfaces. Do not break this paint seal when removing excess paint or finish from the glass or when cleaning the unit.

Painting and Finishing - Interior Finish - All Units

Keep paint and other finishes off weatherstrip, hardware and other vinyl surfaces, such as double hung and slider sash slides. To prevent sticking, keep the sash open while finishing and do not close windows or replace the sash until all surfaces are dry. Lap-paint or varnish approximately 1/16 inch onto glass to seal glazing compound and to provide a moisture stop.

Again, avoid getting any paint on the weatherstripping or other vinyl surfaces. If that happens, please wipe it off immediately. If necessary, clean the vinyl surfaces with mineral spirits. Never use lacquer thinner or other solvents, as they may cause material deterioration.

Care of the Clad Exterior

Occasional cleaning of the exterior aluminum surfaces will help maintain the luster of the original finish. Use a mild soap with water to clean the aluminum surfaces. Stubborn stains and deposits may be removed using mineral spirits. Using tools or abrasive materials on any stains is not recommended, as they may damage the surface. If such damage does occur, contact your Hurd distributor to obtain a color-matched touch-up paint. An application of automotive paste wax will restore the luster to the aluminum cladding.

Glass Cleaning

Normal glass manufacturing processes require the use of surface protection materials to prevent damage during production, handling, shipping and storage. These materials are easily removed by most cleaning agents, with the exception of those containing ammonia. We recommend that you try vinegar and water (diluted 4-to-1) first or a feldspar-based cleansing powder (such as Bon AmiĀ®). After initial cleaning, your regular window-cleaning product can be used effectively. Do not use sharp instruments to clean your glass they can score the glass, which will lead to cracking.

When cleaning the glass, avoid dripping the cleaning agent onto the hardware, especially if the product has a large concentration of ammonia. Always wipe up any spills immediately.

Many Hurd window units have a bedding compound that secures the glass and prevents water infiltration. If some of this compound has oozed onto the glass surface, use a dull scraper to remove it. Once again, a razor blade or sharp knife may lead to seal failures and/or glass cracking.

Window stickers will peel away after they are soaked thoroughly with water.


Due to increased energy efficiency in building materials and design, homeowners are occasionally troubled by condensation, which is characterized by moisture and/or frost build-up on glass or other cold surfaces within the home.

If condensation does occur, quite often the culprit is not leaky or improperly sealed windows, as long as the windows have been properly installed and maintained as described above. The window, instead, indicates that the problem exists elsewhere.

Chances are that there is excessive humidity (water vapor within the air) inside the house. When this water vapor encounters a cooled surface, it will condense on it and possibly form a frost. To eliminate this problem, check your ventilation or control the sources of humidity within your home.
