Deck builders in Long Lake, MN

Homes in Long Lake have a median construction year of 1980, so a deck original to a typical house would now be about 46 years old — beyond the point where wood framing, fasteners and flashing can be assumed sound.

Many decks from the 1970s and 1980s were built before today's detailed deck provisions appeared in model codes. Common issues on decks of this age include corroded hangers, posts set directly in soil and ledger boards fastened with nails. Replacement is often the better value than repeated repairs.

That makes Long Lake's housing 7 years newer than Hennepin County as a whole, where the median home was built in 1973. Statewide, the median Minnesota home was built in 1979. Among the 62 covered Minnesota communities with Census data, Long Lake ranks #20 for oldest housing. In this ZIP code, 20% of homes were built before 1960, 31% between 1960 and 1979, 25% between 1980 and 1999, and 24% since 2000 — the single largest group dates to the 1970s.

The nearest NOAA climate station with 1991–2020 normals is Delano, about 10 miles away. It records an average of 166 days a year with a low at or below 32°F — a long, hard freezing season. On roughly 89 of those days the temperature climbs back above freezing, so water in wood, soil and gaps between boards repeatedly freezes and thaws.

For Long Lake, that means footings must bear below the locally required frost depth to avoid heaving, and wood surfaces should be kept sealed so absorbed water doesn't split boards over winter. Synthetic decking tolerates freeze-thaw well but still needs the manufacturer's expansion gaps.

Snow is a major factor: the Rockford station averages about 45.1 inches a year. Framing has to carry snow load, stairs need a plan for winter use, and snow removal should be done with plastic-bladed shovels and ice-melt products the decking manufacturer allows.

Precipitation averages about 30.6 inches a year, falling on about 58 days with 0.1 inch or more — wet enough that drainage and flashing still matter, but dry spells also let wood surfaces dry out and check in the sun.

Summer heat is mild by comparison — average summer highs near 80°F and only about 8 days a year at 90°F or above — so board color can be chosen mostly on looks.

Budget, upkeep tolerance and sun exposure on your particular lot still decide the final choice between these options.

Long Lake has about 2,185 housing units across its covered ZIP code. 84% are single-family detached homes, 4% are attached homes such as townhouses and rowhouses, and about 12% are in buildings with two or more units. Roughly 87% of occupied homes are owner-occupied.

Detached single-family homes dominate in Long Lake, so most decks are backyard decks attached to the rear of the house. That gives more freedom on size, layout and stairs, and makes a well-planned deck one of the most-used rooms of the home.

• Replacement and major repair: about 963 homes (44%) were built between 1970 and 1999, the age group whose original or early add-on decks are most likely to have worn-out framing, connectors and boards.
• Retrofit decks on older homes: about 695 homes (32%) predate 1970. Here the priority is confirming that add-on decks are properly attached — or rebuilding them freestanding — before any cosmetic work.
• Upgrades and expansions: about 282 homes (13%) were built since 2010. Their decks are usually sound but small or builder-grade, so enlarging the deck, adding stairs and switching to composite or upgraded railings are common.

With about 166 freezing days a year, the building window in Long Lake is compressed. Design, drawings and permits are usually handled in winter so footings can go in as soon as the ground allows in spring, and finishes like stain are applied before nights turn cold in fall.

For Long Lake, MN, ask the permit office whether your deck needs a permit based on its size, height and attachment to the house, which drawings and inspections are required.
