Asphalt Sealcoating & Crack Filling in Spokane, Done the Right Way

Eastern Washington is tough on asphalt. Hot, dry summers, winter freeze-thaw cycles, studded tires, and snow plows all work on the pavement at once. If your driveway or parking lot in Spokane is starting to gray out, ravel, or show a web of cracks, it is time to look at asphalt sealcoating and crack filling before the damage gets deep.

Precision Asphalt Spokane focuses on practical, long lasting protection. We do not treat sealcoating as a quick cosmetic spray. Our approach is to slow down water penetration, UV damage, and oxidation, so your existing asphalt holds up many more seasons. That means we spend as much effort on cleaning and crack prep as we do on the sealcoat itself.

Because we work only in this region, our recommendations are based on local conditions. For example, we pay attention to Spokane County’s winter deicer use, your snow removal practices, and how much shade or irrigation hits the pavement. All of this changes how fast the surface dries out and what mix design will actually last, not just look black for a few weeks.

How We Actually Do Crack Filling and Sealcoating

On every project, we start with an on-site walk through. We look at the thickness of the existing asphalt, base stability, drainage patterns, and the type of cracking. Alligator cracking (tight, blocky patterns) often points to base failure and may need patching, while wider, straight cracks can usually be routed and filled. This first inspection tells us what is worth saving with maintenance and what might need more than just sealcoat.

If the surface is a good candidate, our crew begins with cleaning. We use backpack blowers to clear loose debris, plus steel wire brooms and, when needed, power brooms around heavy dirt or moss near curbs and in low spots. For commercial lots with oil build up, we apply a detergent based cleaner or a specialized oil spot primer, then mechanically scrub those areas. Sealcoat will not bond over oil or fine dust, so this step is non negotiable.

Crack preparation is next. For cracks typically between 1/4 and about 1 inch, we open them slightly with a crack router or saw to create a uniform reservoir with clean, vertical sides. This helps the crack sealant flex instead of popping out in winter. We then blow out dust with high pressure air. Only after that do we install hot rubber crack sealant with a direct fire or oil jacketed melter, depending on job size. The material is applied slightly overfilled, then banded with a squeegee to tie into the surrounding pavement.

Once cracks are sealed and cooled, we spot prime oil soaked areas, polished aggregate, or new patches that need extra bonding help. Then we apply the sealcoat. For most Spokane residential driveways, we use a refined coal tar or asphalt emulsion sealer modified with latex and sand, brushing edges by hand and spraying or squeegeeing the main field. Commercial lots typically get a spray and squeegee combination to force the mix into the surface and get an even, durable film thickness.

Materials, Mix Designs, and Options That Matter in Spokane

Not all “black sealer” is the same. Precision Asphalt Spokane chooses the product type based on how the pavement is used and what it will see in our local climate.

For residential driveways, we typically recommend a high solids asphalt emulsion sealer with added sand for traction. This provides a darker finish with less odor and is friendlier around landscaping, kids, and pets. Where vehicles may drip more oil, we can use a refined coal tar based product if requested, which resists petroleum spills better but has more odor during application.

On busy commercial lots and drive lanes that see delivery trucks and frequent turning movements, we lean toward a heavy duty spec. This often includes higher sand load (for skid resistance and wear) and polymer additives that help the film resist scuffing from power steering and studded tires. On slopes or locations where customers walk from snow and ice into the lot, we adjust sand ratios to reduce slipperiness in winter and early spring.

We also pay attention to cure time. Spokane’s dry air and summer temperatures usually help sealers dry quickly, but shaded locations, heavy irrigation overspray, and cool fall mornings can slow curing a lot. We plan mix water content and start times around the specific site so that lined parking stalls, delivery paths, and ADA routes are back in service as quickly as the product allows, without trapping moisture under the film.

If striping or pavement markings are part of the project, we plan that around the sealer used. Some sealers require a longer wait before paint, especially in shady north facing lots that see less sun. We schedule layout and striping when the surface has fully cured so markings do not peel or track.

When, Why, and How Often to Sealcoat in Spokane

In our climate, unprotected asphalt starts to oxidize within a couple of years. The rich black surface slowly turns gray, then becomes brittle and more prone to cracking and raveling. Sealcoating acts like sunscreen and a raincoat for the pavement. It slows UV damage and keeps water and deicing chemicals from soaking into tiny surface voids.

Most Spokane area driveways benefit from a first sealcoat about 1 to 2 years after new asphalt is installed, then every 3 to 5 years after that, depending on exposure and traffic. Lots with heavy snow plow activity or lots near arterials that get more sand and deicer tracked in may need shorter cycles. A lot that sits mostly in shade and rarely sees heavy trucks can go longer between coats.

Timing matters. We generally schedule asphalt sealcoating and crack filling in Spokane from late April through early October, when pavement and air temperatures reliably stay above about 50 degrees and there is no active rain in the forecast. Performing the work outside that window often results in poor bonding or extended cure times that frustrate owners and tenants.

We also coordinate around your operations. For apartment complexes, we typically break the lot into sections so tenants always have a place to park. For churches, we may schedule work early in the week so everything is open by the weekend. For businesses with heavy daytime traffic, we can arrange early morning or phased work, with clear barricades, cones, and signage to keep people out until the surface is ready.

Costs, Common Problems, and What to Ask Before You Hire

The cost of asphalt sealcoating and crack filling in Spokane depends on several real factors: total square footage, number and width of cracks, how much cleaning is required, how many phases the work must be broken into to keep traffic flowing, and whether patching is needed before maintenance. Larger, open parking lots with simple layouts usually cost less per square foot than small, broken up areas with islands, curbs, and tight access.

We are straightforward with proposals. Precision Asphalt Spokane breaks out line items for crack filling, sealcoating, any patching, and striping so you see what you are paying for. For example, a heavily cracked older lot may need a significant amount of hot rubber crack seal before any sealer goes down. Skipping that step to show a lower price often leads to sealer sinking into the cracks and failing early.

Common issues we solve include puddling water that keeps sealer from curing evenly, heavy oil spots near parking stalls, and previous low quality seal jobs that are peeling. For standing water, we can sometimes correct grade with localized patching or milling in the worst areas before sealing. For oil soaked spots, we may need to cut out and replace the asphalt instead of just priming, if the oil has penetrated deeply.

Before you hire any company for asphalt sealcoating in Spokane, ask a few specific questions. What crack seal material will you use, and will you route or just fill? How many gallons of sealer per 1,000 square feet are included in the price? Will you add sand and, if so, at what rate? How will you handle traffic control and access for tenants or customers? How long will you recommend keeping vehicles off, given the time of year and shade on my property? Clear, detailed answers to those questions will tell you whether the contractor is planning a quick spray and go or a maintenance project that actually protects your pavement investment.
