Fix It, Rebuild It, or Start Over?
Deck Builders in Northglenn get one question more than any other: is my deck worth repairing? It is a fair question in a city that Jordon Perlmutter laid out as a master-planned community in 1959 and that incorporated on April 19, 1969. Plenty of houses here have had a deck added, rebuilt or patched at some point in the decades since, and the framing underneath is not always as sound as the boards on top. We start every Northglenn visit by getting under the deck before we talk about anything else.
What we check before giving an answer
- Footings and posts: settling, rot at the base, posts smaller than the 6x6 minimum the DCA 6 guide calls for
- Ledger: whether it is bolted and flashed, or just nailed to the rim
- Joists and beams: soft spots, splits and over-long spans
- Railings: wobble, height and any post that moves under hand pressure
- Stairs: loose stringers, uneven risers and missing handrails
If the frame is solid, new decking and railings can give an old deck years more life. If the frame fails, resurfacing it just hides the problem, and we will tell you so.
Designing for a tight lot
Northglenn fit 38,131 people into about 7.35 square miles of land at the 2020 census, or roughly 5,187 per square mile. Yards are smaller and neighbors are close. That pushes us toward low, ground-level platforms that may not need guards, built-in benches instead of freestanding furniture, and a layout that keeps setbacks and easements clear. A small deck that is well planned often gets more use than a large one squeezed against the fence.
March snow is the heavy one
1991 to 2020 climate normals for Northglenn show about 44.8 inches of snow a year, and March is the snowiest month at about 8.2 inches. Spring snow tends to be wet and dense, which is the load a deck frame really has to carry. We size joists, beams and footings to the local design criteria and leave the inspector nothing to question. If you plan a pergola or a solid roof over the deck, snow load drives that design even more.
Wide temperature swings move wood
The recorded range here runs from minus 24 degrees in December 1990 to a 108-degree August afternoon in 2008. Boards expand and shrink through that swing, fasteners loosen, and stain cracks. For repair work we replace popped nails with screws or hidden fasteners and gap new boards correctly for the material. For replacements, composite and capped boards handle the swing with less upkeep than softwood.
Landlords and long-time owners
Census estimates put Northglenn's owner-occupancy at 60.6%, so a fair share of decks here sit behind rental homes. A safe, solid deck matters as much for a tenant as for an owner. We can quote a straightforward repair that brings railings and stairs up to current practice, or a full replacement, and itemize both so you can compare.

Northglenn Questions
How do I know if my Northglenn deck needs replacing instead of repair?
Look at the structure, not the surface. Rot at the post bases, a ledger that was never flashed, sagging joists or footings that have shifted usually mean replacement. Weathered or cupped boards on a sound frame can often be swapped out.
Can I put new composite boards on my old wood frame?
Sometimes. Composite often needs closer joist spacing than wood, and the frame has to be in good shape, because new composite boards can easily outlast a tired wood frame underneath them. We check spacing and condition before recommending it.
My yard is small. Do I still need a permit for a low deck?
Rules depend on height, size and whether the deck attaches to the house, and they are set by the city. We confirm the requirement for your specific plan before work starts and pull the permit when one is needed.
Do you work on rental properties in Northglenn?
Yes. We can quote safety repairs to railings and stairs, a full rebuild, or both, itemized so an owner or property manager can decide.
