Renton siding contractor
Renton has two big waves of housing that now need new siding: post-war ramblers and split-levels, and the 1990s–2000s subdivisions whose hardboard and early composite siding is wearing out. Here is how to tell what you have and what to budget.
Renton homes

Most calls we get about siding replacement in Renton, WA come from homes built in one of two eras. In the Highlands and Kennydale, it is often a 1950s–1970s rambler or split-level with painted cedar, plywood panels or a later layer of vinyl. In Fairwood, Benson Hill and Talbot Hill, it is frequently a two-story home from the 1990s or early 2000s, built fast during a subdivision boom and sided with hardboard or an early composite lap board.
Hardboard lap siding was widely used in that period because it was affordable and looked like painted wood. Its weakness is water. When paint wears thin or the bottom edges and nail holes are left unsealed, the board absorbs moisture, swells, and eventually softens or crumbles. The usual signs are:
A few damaged boards can be replaced with a siding repair, but a matching hardboard product is often hard to find, and once the problem shows up on several walls, it usually continues. That is when a full siding replacement makes more sense.
Single-story ramblers are among the most economical homes to re-side: low walls, easy access and simple rooflines. Split-levels add transitions between levels and garage walls that are often the first to show rot. On both, we check the sill area near grade, where older homes sometimes have soil or bark piled against the siding.
Renton planning ranges run about 8% above our regional base, lower than Seattle and the Eastside. Many owners here choose vinyl siding for the lowest upfront cost or LP SmartSide as a direct, more durable replacement for the wood-look hardboard they already have. Fiber cement is the pick when long-term moisture resistance is the priority.

Renton questions
Answers for Renton homeowners weighing repair against replacement. More in our siding FAQ.
Hardboard is common on homes built in the 1990s and early 2000s. It often has an embossed wood grain, sounds dull when tapped, and swells at the bottom edges when wet. We confirm it during the inspection, sometimes by checking a stamp on the back of a board.
If the damage is limited to a few spots, yes. The challenge is matching the profile, since many older hardboard lines are no longer made. When several walls are affected, re-siding usually costs less over time than repeated patching.
Usually. Ramblers have less wall area and are easier to reach, so staging and labor go down. The ranges on this page are for a two-story home; use the estimator with your home size for a closer number.
LP SmartSide and fiber cement lap both keep the painted-wood look and handle moisture far better. Vinyl is the budget option. Compare the details on our LP SmartSide page.
