About Sunnyside (Lake Whatcom)
Sunnyside, located along the eastern shore of Lake Whatcom in Whatcom County, Washington, is a scenic community offering serene lake views, lush green landscapes, and a mix of waterfront and inland properties. The area is renowned for its picturesque surroundings, including dense forests, rolling hills, and abundant recreational opportunities, which make it an appealing destination for homeowners looking to combine a natural, tranquil lifestyle with proximity to outdoor activities. However, the unique environmental conditions in Sunnyside—specifically its proximity to the lake—create different weatherproofing challenges for coastal versus inland properties. This essay will compare the strategies used to protect homes from the elements based on their proximity to water, and discuss how moisture, UV exposure, and weather factors like wind-driven rain can impact siding longevity.
Homes near Lake Whatcom face heightened moisture levels due to the large body of water, particularly during the rainy months when humidity is higher. The proximity to the lake also means homes in this area are more susceptible to increased moisture, which can lead to wood rot, mold, and mildew if not managed properly. Wind-driven rain can also be a significant issue, especially during the fall and winter months when storms are more frequent. These conditions can force moisture into cracks, seams, and gaps in siding, contributing to the deterioration of materials over time. Although Sunnyside is not directly on the ocean, the area still experiences elevated moisture levels, which can compromise the longevity of traditional siding materials. Additionally, UV exposure is a concern in sunnier months, as the sun’s rays reflect off the lake’s surface, exacerbating fading, cracking, and warping in siding materials that are not protected.
To combat these challenges, homes near the lake should consider using fiber cement siding. Brands like James Hardie offer fiber cement products that are highly resistant to moisture and humidity, making them ideal for homes in areas like Sunnyside. Fiber cement is also resistant to mold and rot, making it a durable option for properties in damp environments. Unlike wood siding, fiber cement does not absorb moisture, which helps prevent issues such as mold growth and premature deterioration. Additionally, fiber cement siding is UV-resistant and will not fade or crack as quickly as traditional wood siding, making it a good investment for properties with high sun exposure. Engineered wood siding can also be a suitable alternative if coated with a high-performance, water-resistant finish, though it requires more frequent maintenance than fiber cement.
Another option for waterfront homes in Sunnyside is the installation of a rainscreen system behind the siding. A rainscreen creates an air gap between the siding and the home’s sheathing, allowing moisture to escape rather than being trapped against the house. This can help reduce the risk of water damage and mold growth. Stainless steel or galvanized fasteners are a good choice for homes near water, as they are resistant to rust and corrosion from the increased moisture levels. Regular painting or sealing of wood siding is also essential to protect it from the elements and maintain its appearance.
Inland homes in Sunnyside, though not directly impacted by the lake’s moisture, still face weather-related challenges. The region receives substantial rainfall throughout the year, and areas near Lake Whatcom, especially those situated in low-lying or shaded areas, can experience high humidity levels. While these homes are not exposed to salt air, they can still be prone to moisture accumulation, which leads to similar issues as those found in coastal homes, such as wood rot and mold. Wind-driven rain can still be a concern, particularly during storms, and homes located in areas with poor drainage or inadequate ventilation may experience water intrusion in hidden areas, leading to potential structural damage. Additionally, fluctuations in temperature between cool, wet winters and dry, hot summers can cause siding materials to expand and contract, which may eventually lead to cracking or warping.
For inland homes, fiber cement siding remains an excellent choice due to its resistance to moisture and durability. Vinyl siding with insulated backing is another good option for homes in Sunnyside, as it is low-maintenance and helps with energy efficiency by providing additional insulation. Proper ventilation and regular maintenance are key in preventing mold and rot issues in inland properties. Installing vapor barriers and ensuring proper flashing around windows and doors will help reduce the risk of moisture penetration. Maintaining gutters and downspouts to ensure proper water drainage away from the home is another crucial step in keeping siding intact and preventing water damage.
Sunnyside is iconic for its serene lakefront living and access to outdoor recreational activities, such as boating, fishing, hiking, and kayaking. The stunning views of Lake Whatcom and the nearby mountains create an atmosphere of tranquility that attracts those looking to escape from the hustle and bustle of urban life. The area is also known for its proximity to Bellingham, which provides easy access to the amenities of a larger city while maintaining the peaceful charm of rural living. What sets Sunnyside apart from other locations in Whatcom County is its balance of scenic beauty, recreational opportunities, and convenience.
Purchasing a home in Sunnyside can be a smart decision for those seeking a peaceful lifestyle surrounded by nature. The area offers an attractive mix of waterfront and inland properties, with relatively affordable prices compared to other waterfront regions. However, prospective buyers should be aware of the challenges associated with maintaining a home in a climate with high moisture levels. Properties closer to Lake Whatcom will require more frequent maintenance and weatherproofing, especially for homes with wood or older siding. Buyers should factor in the cost of weatherproofing and the potential for increased maintenance when considering homes near the lake.
Homeowners in Sunnyside should expect to perform rot repair from time to time, particularly those with wood siding. Coastal homes or homes near the lake will experience more frequent repairs due to moisture exposure, while inland homes may require repairs every few years, depending on the type of siding and the amount of moisture exposure. Regular inspections of siding, gutters, and roof flashing are essential for detecting any water intrusion and preventing more serious issues. Homes with fiber cement or vinyl siding will experience fewer issues with rot and deterioration, but wood siding will require more attention and regular sealing.
Nearby landmarks include Lake Whatcom itself, which is a popular destination for boating, fishing, and swimming. The nearby Whatcom Falls Park offers hiking trails, picnic areas, and beautiful waterfalls, while the Mount Baker Wilderness area provides opportunities for hiking, climbing, and skiing. The Chuckanut Drive Scenic Byway offers stunning views of the lake, surrounding forests, and the North Cascades, making it a must-see for visitors and residents alike.
In conclusion, Sunnyside offers an idyllic living environment with stunning views and easy access to outdoor activities. Whether coastal or inland, homes in this area require proper weatherproofing strategies to protect against moisture, humidity, and UV exposure. Fiber cement siding is highly recommended for homes near the lake, as it provides long-lasting protection against water damage, UV rays, and rot. Regular maintenance and weatherproofing are essential for ensuring the longevity of homes in Sunnyside, allowing homeowners to enjoy the beauty of Lake Whatcom and the surrounding area for years to come.
