Siding, Roofing, Windows & Decks in Mount Vernon, WA

Mount Vernon’s homes have a median year built of 1989, and the housing splits almost evenly between houses from 1980–99 and houses built since 2000. That puts a lot of exteriors at the age when original siding, roofs and early vinyl windows start coming due at the same time. Builders Service Company replaces siding, roofing, windows and decks for homeowners here and across Skagit County. Below you’ll find what is on local homes today, the materials we usually recommend for each service, and how to schedule a free in-home consultation where we look at your house and talk through the options with you.

Homes in Mount Vernon: what’s on them now

Census data puts the median year built at 1989, and no single era dominates: 32% of homes were built in 2000 or later, 30% from 1980 to 1999, 27% from 1950 to 1979 and 12% before 1950. Newer construction is still being added, and the city has 13,623 housing units in all.

Each era brings its own exterior issues:

  • 2000 or later: builder-grade vinyl or fiber cement siding reaching its first repaint or replacement, plus builder-grade windows.
  • 1980–1999: the era of composite and hardboard siding, including LP siding with its known history of moisture failure, and first-generation vinyl windows.
  • 1950–1979: cedar or T1-11 siding, and sometimes asbestos-cement shingles, which may contain asbestos and should be tested before removal. Aluminum or early vinyl windows are common.
  • Before 1950: likely original wood lap siding, possible lead paint and single-pane or early windows.

Detached houses make up 61% of the housing, with 13% attached homes, 20% apartments and 6% mobile homes. Sixty percent of homes are owner-occupied, and the median home value, about $470,000, sits right at the Skagit County median. Parts of town lie in the valley flood plain. Building permits for exterior work inside city limits are handled by the City of Mount Vernon.

Siding in Mount Vernon

Most siding work in Mount Vernon is on houses built from 1980 on. Homes from 2000 or later, 32% of the housing, often have builder-grade vinyl or fiber cement that is reaching its first repaint or replacement. On 1980s and 1990s houses, hardboard and LP siding is what usually comes off. When we replace it, these are the types we usually recommend:

  • Vinyl siding: the most versatile and least expensive option, and a practical choice for a tight budget or a large wall area.
  • Evergreen Shield Siding System: our exclusive insulated composite siding, designed for the Pacific Northwest climate. Its insulating graphite membrane gives a thermal resistance of R-2.0, compared with R-0.61 for standard vinyl. Census data shows 46% of homes here heat with electricity, and where heating is costly, insulated siding pays back more. The composite is also built for water resistance through long wet seasons, humidity, mold and mildew.
  • Metal siding: a clean, modern option for the whole house or for sections of it.
  • Stacked stone and stone veneer: accent cladding for wainscots, entries, columns and chimneys, paired with any of the siding above to add curb appeal and a durable base course.

None of the three siding types is wood, so none of them will rot the way old wood and hardboard siding can. The best option for your home depends on its age, condition and your goals, and we work through that with you during the free in-home consultation.

Roofing in Mount Vernon

Roofs in the Skagit Valley have to handle wind as well as rain, and valley wind is one of the area’s distinct local conditions. We focus on proper sealing, flashing and ventilation, with materials selected for strength and weather resistance, so the roof stays intact through wet, windy months.

We install two main roof types and give them equal weight:

  • Asphalt shingle roofing: versatile and available in a range of textures and colors to suit most house styles.
  • EDCO metal roofing: the metal roof we install, for homeowners who prefer metal panels over shingles.

Which one fits depends on your house, your budget and how long you plan to stay, and we compare them side by side at the consultation.

Housing age shapes the job too. About 27% of homes date from 1950 to 1979, and on houses that old we check the roof’s age and whether more than one layer of shingles is in place before tear-off. Mobile homes make up 6% of the housing, and their low-slope manufactured-home roofs call for a different approach than a pitched house roof.

On every reroof, our crews use ladder stabilizers and standoffs so ladder weight rests on the roof instead of your gutters. Old roofing material goes into a container on site for proper disposal, and when we are not working, the roof is covered with tarps to keep rain out.

Windows in Mount Vernon

Many windows in Mount Vernon are first-generation vinyl. Homes built from 1980 to 1999 make up 30% of the housing, and windows from that era are where failing seals tend to show up. Houses built since 2000 usually have builder-grade windows, and older homes may still have aluminum frames or single-pane glass.

Heating cost matters for windows as much as for siding. Census data shows 46% of homes heat with electricity and 51% with gas, and where electric heat is common, efficient windows pay back more. PSE is the electric utility; check with PSE for current programs before you order.

We install Preservation 9000 vinyl replacement windows, and we are the exclusive provider of Preservation 9000 windows in Washington. Styles include:

  • Double-hung and slider windows
  • Casement, awning and hopper windows
  • Picture and garden windows
  • Bay and bow windows
  • Custom shapes

Matching the style to the room helps. Sliders or casements suit upper floors and tight eaves. Casement, awning or hopper windows help ventilate kitchens and baths. Picture, bay and bow windows open up a view. We measure every opening and go over style and color choices during the free in-home consultation.

Decks in Mount Vernon

Sixty percent of homes in Mount Vernon are owner-occupied, and long-term owners are the ones most likely to invest in an outdoor space they will use for years. We design and build custom decks tailored to your home and yard, for relaxing, entertaining and family use.

We build with three materials:

  • Composite decking: no rot and no staining, a good fit for decks that stay damp or shaded much of the year.
  • Vinyl decking: also rot-free and stain-free, with an easy-to-clean surface.
  • Wood decking: a natural look and a budget-friendly starting point, with regular sealing to keep it sound.

On any material, we plan for drainage and a slip-resistant surface so the deck stays safe in wet months. Parts of town lie in the Skagit Valley flood plain, so we review your lot’s conditions with you before we design the deck. Wildfire risk is rated Low, at the 54th percentile in the state.

Mount Vernon siding, roofing, window and deck FAQ

What siding should replace the hardboard on my 1990s house in Mount Vernon?

Vinyl, the Evergreen Shield Siding System or metal siding are the types we usually recommend when hardboard comes off, and none of them is wood. Vinyl is the least expensive option. The Evergreen Shield Siding System adds insulation and 20 built-in, fade-resistant colors that resist chipping, peeling and fading. We help you choose during a free in-home consultation.

How do you protect my gutters and yard during a roof replacement?

Our crews use ladder stabilizers and standoffs so ladder weight rests on the roof, not on your gutters. Old roofing goes into a container on site for proper disposal, and the roof is covered with tarps whenever we are not working so rain stays out. We install asphalt shingle and EDCO metal roofing, and our work comes with a lifetime warranty.

Are there rebates for new windows in Mount Vernon?

PSE is the electric utility, so check with PSE for any current programs before you order windows.

Who handles permits for exterior projects in Mount Vernon?

Whether your siding, roofing, window or deck project needs a permit depends on the scope of the work, and we review what applies to your project during the free in-home consultation. Our Washington contractor license number is BUILDSC027JN.

Do I need fire-resistant decking in Mount Vernon?

Wildfire risk is rated Low, at the 54th percentile in the state, so most deck choices come down to moisture, maintenance and budget. We build with composite and vinyl decking, which will not rot and need no staining, and with wood, which offers a natural look with regular sealing. We help you pick a material and layout at the free consultation.

My house was built before 1950. What should I know before residing it?

About 12% of Mount Vernon homes were built before 1950, and houses that old likely have original wood lap siding and possible lead paint. We look at the walls during a free in-home consultation and then go over the types we usually recommend: vinyl, the Evergreen Shield Siding System and metal siding, with stacked stone or stone veneer accents for entries and wainscots.

  • Mason and team did a great job on our remodel. We did a new roof, vinyl siding and gutters. Big project on a very old home (over 100 years old and on a steep hill) but the team handled it with ease.
