The plaintiffs brought an action in the Superior Court seeking a declaratory judgment that they were entitled to coverage for the loss described under their homeowner’s insurance policy which had been issued by the defendant, Massachusetts Bay Insurance Company (Massachusetts *236 Bay). The action arose out of the migration of home heating oil onto the plaintiffs’ property after the oil was negligently spilled at a neighbor’s home. The insurance policy included coverage for loss or damage to property. The policy, however, excluded from coverage “loss . . . caused by . . . release, discharge or dispersal of contaminants or pollutants . .'. .” Massachusetts Bay denied that its policy covered the plaintiffs’ loss, relying on the “contaminants or pollutants” exclusion. The plaintiffs claimed, however, that their loss was caused by the negligence of others for which there was coverage under Massachusetts Bay’s policy. Both parties moved for summary judgment. After listening to the arguments of counsel, the motion judge granted the plaintiffs’ motion for summary judgment and denied Massachusetts Bay’s motion. It appealed the ensuing judgment for the plaintiffs.
Prior to the hearing before the motion judge, the parties stipulated the following. The plaintiffs’ residence in Granby abuts and is downgrade from a residence at 26 Cedar Drive. Number 26 was heated by oil and was originally equipped with a fuel storage tank in the basement. At some point, previous owners of the property at 26 Cedar Drive decided to remove the fuel storage tank from the basement and to install an underground storage tank in their yard.
One or more of the following events then took place: (1) the previous owners of 26 Cedar Drive either (a) negligently failed properly to remove or seal the disconnected fuel oil delivery line that led into the basement, or (b) negligently removed or altered the seal on the disconnected fuel delivery line; or (2) the current owners of 26 Cedar Drive negligently failed to direct delivery of heating oil into the correct fuel delivery line; or, (3) an oil delivery company, making a delivery for the current owners, negligently failed to determine whether the fuel delivery line into which it delivered oil was properly attached to a fuel storage tank at 26 Cedar Drive.
As a result of one or more of the above negligent acts, approximately 500 gallons of fuel oil was pumped through the disconnected fuel delivery line into the basement of the home at 26 Cedar Drive through the disconnected fuel deliv *237 ery line. The oil then seeped out of the basement and migrated underground to the plaintiffs’ property. It contaminated the plaintiffs’ well and caused other damage to the plaintiffs’ property.
In granting the plaintiffs’ motion for summary judgment, the motion judge ruled that the case was controlled, in all material respects, by our decision in
Standard Elec. Supply Co.
v.
Norfolk & Dedham Mut. Fire Ins. Co.,
The court ruled that the plaintiff could recover for its loss, citing as basis for its ruling, “the well established principle that recovery on an insurance policy is allowed ‘where the insured risk itself set into operation a chain of causation in which the last step may have been an excepted risk ....’” Id. at 765, 766, quoting from Appleman, Insurance Law and Practice, § 3083, at 311.
Here, the parties stipulated that, as a result of one or more negligent acts that occurred on the adjacent property, fuel oil seeped underground and damaged the plaintiffs’ property. Massachusetts Bay’s insurance policy covered losses caused by the negligence of others.

That covered event, like the

Standard Elec. Supply Co.
v.
Dedham Mut. Fire Ins. Co., supra,
set in motion a chain of circumstances that resulted in the contamination of the plaintiffs’ wells, a loss that constitutes an event excluded under the policy. However, where the excluded event is not the cause of the loss, but rather the
result
of a covered risk, the insured may recover.
Standard Elec. Supply Co., supra
at 766. See
Bet-tigole
v.
American Employers Ins. Co.,
At the hearing on the summary judgment motions, Massachusetts Bay raised, for the first time, the claim that the plaintiffs’ loss was excluded under two additional clauses, specifically (1) “[A]cts or decisions, including the failure to act or decide, of any person, group, organization or governmental body” and (2) “faulty, inadequate or defective . . . design, specifications, workmanship, repair [or] construction. . . .” The motion judge ruled that Massachusetts Bay had failed timely to assert those defenses and, therefore, had waived them. The judge entered a judgment declaring that plaintiffs have coverage under the policy. On appeal, Massachusetts Bay claims that the judge committed error and that the plaintiffs’ claim is excluded under those clauses.
It is obvious from this record that Massachusetts Bay was indeed late in setting up the two additional exclusion clauses as defenses. Assuming, without deciding, that such tardiness did not amount to a waiver, we hold that the two clauses do not bar recovery.
Massachusetts Bay concedes that its insurance policy cov- L ers negligent acts that cause covered losses. It argues, however, that the “acts and decisions” clause excludes coverage where negligence causes an excluded loss, as here. The clause, as Massachusetts Bay recognizes, cannot be taken lit
*239
erally. If it were to be so taken, it would exclude coverage from all acts and decisions of any character of all persons, groups, or entities. Such an interpretation would leave the insurance policy practically worthless. “Exclusions from insurance coverage are to be strictly construed . . . [and] any ambiguities in insurance contracts are to be resolved against the insurer.”
Quincy Mut. Fire Ins. Co.
v.
Abernathy,
Massachusetts Bay’s argument that the “faulty design” clause excludes coverage is also without merit. The parties stipulated to certain negligent acts and omissions, one or more of which caused the loss. None of those stipulated acts or omissions could be construed as faulty, inadequate, or defective workmanship, design, specifications, repair, or construction.
The granting of the plaintiff's’ motion for summary judgment was not error.
Judgment affirmed.
Notes
Massachusetts Bay argues that the misdelivery of the fuel oil at the adjacent premises was the “release, discharge and disposal” of “contaminants” in this case and therefore, was the excluded event under the poli *238 cy. However, that argument ignores the fact that Massachusetts Bay had stipulated that one or more negligent acts caused the release of the fuel oil. It is not disputed that negligence is a covered risk under the policy.
